findBy when there could be more than one I'm using a findBy query in a grails/gorm project, where there is usually only one result (and I only ever want one result). However, there could occasionally be two (or even three theoretically, though it hasn't happened yet). How can I tell GORM which one to return, when there are more than one? I'm looking these up by an ID in an external system, which will eventually roll back around when it hits a max, so we can have two rows in our data base for the same external ID. I will always want...

Very basic question... Looking at the External Config plugin, it says in the release notes "Notice, that from Grails 7, this plugin is released at a part of Grails core!". Does that mean I don't need to use

implementation 'dk.glasius:external-config:4.0.1'

and can just use the grails.config.locations as if it is part of Grails (which it presumably is as of 7)?

I have been converting a simple Grails 6 app to Grails 7, and I'm getting there, but I keep getting a 'unable to resolve class org.apache.commons.lang.time.DateUtils' error, and others also from the commons.lang package. In Grails 6 and earlier one didn't need to declare a dependency for this, it was built in. It tried declaring a dependency with: implementation 'org.apache.commonscommons lang33.13.0' but that didn't help. Also are groovy-dateutil and groovy-datetime part of core now?

I have an API server based on Grails 6.2.3 running on JDK17. I should allow access to the API via a token and I would like to use it for an Angular FE app. Security is via a token and I allow users to login to access their data in Angular. I have used Spring Security in the past and want to leverage this again. Although a bit dated I am following the steps shown in this post - https://www.djamware.com/post/58a53b5180aca748640ce350/securing-rest-api-with-grails-3-and-spring-security-rest I have added the following two imports for security 1. implementation "org.grails.pluginsspring security core6.1.2" 2. implementation "org.grails.pluginsspring security rest6.0.0-M1" Unfortunately I go round in circles with dependencies and errors such as the following, Can anyone help me progress and solve this? Have others got Spring Security 6 working with Grails 6.X as I suggest above?

I have to say I'm getting rather frustrated with my attempts to test out Grails 7.0.0-M5 with the conversion of a pretty simple Grails 6 app. I've got it to compile but I can't get it to run - I've run into error after error, which I'll post about in another message. I wondered whether my problems might be caused by using Application Forge - I generated the shell of the app (build.gradle, etc.) with that and then copied over the actual source code of my app and added dependencies to build.gradle. So I thought I'd try another approach, simply using 'grails create-app', and even this generates a bunch of errors (although the app does get created). Can anyone explain what's going on here? $ grails create-app newapp Resolving dependencies...............

hello, Im using Grails 6.2.3 and was looking for an Audit solution. I came across the "Grails Audit Logging Plugin" which should suit what I want. I see I probably have to use version 4 of this. https://grails-plugins.github.io/grails-audit-logging-plugin/6.0.x/#description Anyone else using this? Any known caveats and/or alternatives wrt working with Grails 6 I should be aware of?

Anybody know if there was ever an accounting system build in Grails ?

Not a showstopper, more a curiosity, as it doesn't appear to cause any problems, but... At some point in attempting to build or run a Grails 7 app, converted from Grails 6, a new directory has been created called 'USER_HOME_IS_UNDEFINED'. It contains a '.grails' directory.

Sorry, me again, peppering you with problems... So, as mentioned, I got my converted Grails 7 app to run fine with './gradlew bootRun'. So I thought I'd try deploying a .war to Tomcat and this is very odd! Basically nothing happens. The .war is correctly expanded, and it appears to go through the process of deployment: 24-Jul-2025 181357.851 INFO [main] org.apache.catalina.startup.HostConfig.deployWAR Deploying web application archive [/opt/tomcat/webapps/socialsupermarket.war] 24-Jul-2025 181358.309 WARNING [main] org.apache.tomcat.util.descriptor.web.WebXml.setVersion Unknown version string [5.0].

Try as I might I cannot get my Grails 7.0.0-M5 app to start up with an embedded Undertow server - it always starts up with Tomcat. What am I overlooking? This is the relevant section from build.gradle: implementation "org.apache.grails:grails-core" //implementation "org.springframework.boot:spring-boot-starter-tomcat" implementation "org.springframework.boot:spring-boot-autoconfigure" implementation "org.springframework.boot:spring-boot-starter" implementation "org.springframework.boot:spring-boot-starter-actuator" implementation "org.springframework.boot:spring-boot-starter-logging" implementation "org.springframework.boot:spring-boot-starter-undertow" implementation "org.springframework.boot:spring-boot-starter-validation" I have commented out the Tomcat dependency and added Undertow, but still it uses Tomcat 10.

AWS Elastic Beanstalk and Tomcat 9 throws FileCountLimitExceededException on Spring Boot App I have a Grails 3.1 application that uses Spring Boot version 1.3.7.RELEASE. It's deployed on AWS Elastic Beanstalk using the platform "Tomcat 9 with Corretto 8 running on 64bit Amazon Linux 2/4.9.1". The application has several forms submitting data with multipart/form-data. Suddenly, without any changes in the application code or configuration, POST requests from these forms started to fail with the FileCountLimitExceededException. My question is: How can I properly configure or fix this...

Hey everyone, I am doing a project in grails and just wondered if there is any way to conditionally render something depending on the user role using taglib, something like

<sec:ifAnyGranted roles="ROLE_ADMIN">
    <button>Admin Action</button>
</sec:ifAnyGranted>

I have this import at the top of the page, however it doesn't seem to work

<%@ taglib prefix="sec" uri="<http://grails.org/plugins/spring-security-core>" %>

I do have spring security in the dependencies in build.gradle and refreshed the build I'd appreciate any help or guidance with that My grails version is 6.2.3

I upgraded my grails application from 5.2 to 6.2.3 and everything works great when I run it locally via bootRun in Intellij. When I deploy to a container and run the built jar my .gson views are not found. Has anyone else had a similar issue? (note that our deployment/run method has not changed with the upgrade..it seems like the gson views are either not present in the jar file and/or not compiled properly).

I’m currently using Grails 2.5.6 and trying to build a WAR file (

grails dev war

) without any front-end files that I don’t need. • First, I tried excluding them in

Config.groovy

using:

grails.assets.excludes = [
    "**/*.gsp",
    "**/*.js",
    "**/*.css",
    "**/*.ts",
    "**/*.png",
    "**/*.jpg",
    "**/*.jpeg",
    "**/*.gif",
    "**/*.svg",
]

However, the

.gsp

files were still included in the WAR. • Next, I tried excluding them in BuildConfig.groovy:

grails.project.war.excludes = [
    '**/*.gsp',
    'WEB-INF/grails-app/views/**/*'
]

grails.war.resources = { stagingDir ->
    delete(includeEmptyDirs: true) {
        fileset(dir: "${stagingDir}/WEB-INF/grails-app/views") {
            include(name: '**/*.gsp')
        }
    }

    def pluginsDir = new File("${stagingDir}/WEB-INF/plugins")
    if (pluginsDir.exists()) {
        delete(includeEmptyDirs: true) {
            fileset(dir: pluginsDir.absolutePath) {
                include(name: '**/*.gsp')
            }
        }
    }

    delete(includeEmptyDirs: true) {
        fileset(dir: "${stagingDir}/WEB-INF/classes") {
            include(name: '**/*_gsp.class')
        }
    }
}

But the .gsp files are still being packaged. Question: How can I reliably remove all

.gsp

files from the WAR file in Grails 2.5.6?

Good afternoon, everyone. How's it going? I'm working on a project using Grails 2.5.6. We're currently in the process of upgrading to Grails 4. However, when generating the WAR file for this project, I'm encountering the following error:

| Error WAR packaging error: archive contains more than 65535 entries.

From what I understand, this error is due to a limitation in the ZIP format. I saw some recommendations to use ZIP64, but it seems it's not supported in my current version. Does anyone know of any alternative solutions to resolve this issue?

Hello, Trying to upgrade to Grails 7 from Grails 6 using 7.0.0-M5. In one of my submodules/plugins under the plugins folder of the main app, I have a handful of gsps. On the main app bootRun I get this error that I don't see in Grails 6. I only put a very basic test.gsp in there as a test under a docs folder, see image. Any suggestions out there? Exception in thread "main" java.util.concurrent.ExecutionException: BUG! exception in phase 'semantic analysis' in source unit 'gsp_ic_docstest_gsp.groovy' Cannot invoke "String.equals(Object)" because "packageName" is null.

hey team, I'm revisiting grails again and trying to setup my IDE. I remember IntelliJ had a grails context support but it doesn't seem to be working now. Is there a 3rd party one that supports grails quite well?

May I suggest "team" or "everyone" or "folks"? Not everyone here is a guy.

Hi Colin, Yes, we have a Grails 6 app using Spring Security with our Angular app using cookies at /app/ws and REST at /app/api. We struggled for a while getting the /app/api mapping to stop issuing cookies but finally figured out that it was a configuration issue in our Spring Auth Filters. The config is:

plugin:
    springsecurity: # Spring Security Plugin Configuration
      rest:
        token:
          storage:
            jwt:
              secret: "Some secret key to dev, hope this is long enough."
              expiration: 14400 # default expiration to 4 hours
          validation:
            enableAnonymousAccess: true
      filterChain:
        chainMap:
          - pattern: '/api/appVersion'

Hi team, is it possible to add Spring Security to a Grails 7 RC1 app yet ? Dependency seems wrong here https://apache.github.io/grails-spring-security/7.0.x/core-plugin/guide/index.html , I can't see it in https://start.grails.org/ features

Grails app + tomcat + spring boot - Memory usage is increasing while the application is idle I started to test docker to run my application and I had noticed my memory consume when use "docker stats". I see the memory used from the container increasing like, every f5 on my page or when my application still running but with no one action beeing made on the page. To have a short test, i cleaned one controller and leave it the most clean possible, like: package test class exampleController { def dataSource; static allowedMethods = [save: "POST", update: "POST", delete:...

Hello everyone, hope you’re doing well. I’m currently working on a project using Grails 2.5.6, and we’re in the process of upgrading to Grails 4. For now, I need to generate the WAR file, which I usually do with the command:

grails dev war

For some builds, I’d like to exclude asset files. I tried using the following command:

RUN ./grailsw -Dgrails.env=[env] -Dgrails.war.exploded=true -Dgrails.assets.excludes="**/*.js,**/*.css,**/*.ts,**/*.scss,**/*.sass" war

However, this command does not actually exclude the assets. Is there another way to exclude assets through the command line?

Hi all, I’m trying to upgrade my Grails 6.2.3 app to Grails 7, and I generated a brand-new Grails 7 project from Grails Forge. I picked • Grails 7.0.0-RC1 • Gorm MongoDB • Spring Boot Starter Tomcat • a few additional features (Gradle buildSrc, Grails web console, ect) to make it similar to my app Then in IntelliJ IDEA 2025.2 (latest version of IDE and plugins) I made sure to use JDK 17 (aarch64 distribution, as I’m on Apple silicon). My

build.gradle

is this

plugins {
    id "war"
    id "idea"
    id "eclipse"
}

apply plugin: "org.apache.grails.gradle.grails-gson"

    maven {
       url = '<https://repo.grails.org/grails/restricted>'
    }
}

    useJUnitPlatform()
}

When IntelliJ syncs the project I get the error

The same occurs for the other 2

and then the same

Hey everyone, I am using grails 6.2.2. I am facing an issue where the views in the plugin are not updated when I make changes to them. If I make changes to the view in a plugin the. I have to restart the whole app. However, the views in the main project are updated. Is there anyway I can fix this issue?

Hello, in the process of upgrading from Grails 6 to Grails 7.0.0-RC1. Running into this below exception from our SQL Server database with Grails 7, but not with Grails 6. We are using multiple data sources defined in application.groovy. For this specific [blah] data source, we are using 2 different schemas with a default_schema of dbo. Either schema being used is defined in its proper domain. For Grails 7, is there was some kind of update in gorm where we need to specifically define schema level multi tenancy where we did not have to in Grails 6?
