As to your question: given that the gradle version you're using is ancient, most likely the palantir docker plugin just doesn't support that version anymore. Also note that the plugin itself doesn't seem to be actively supported anymore: https://github.com/palantir/gradle-docker

let me delete from one post

My first suggestion would be to attempt to upgrade to a more recent version of gradle. Besides that, running your build with

--stacktrace

might give more details on the actual error.

Rashid

09/25/2023, 9:37 AM

i can understands that palantir docker plugin does' not support it ..but your requirement to run in that version only

Niels Doucet

09/25/2023, 9:37 AM

well, try an older version of the plugin?

Rashid

09/25/2023, 9:38 AM

i will check with stackstrace but ....if i used gradle version 4.5 or 7.4...getting same error

Rashid

09/25/2023, 9:40 AM

got error

im thinking in build.gradle something im missing which i cannot understand

Niels Doucet

09/25/2023, 9:42 AM

Copy code

* Where:
Build file '/root/PostmanCollectionToOAS/build.gradle' line: 35

It mentions a specific line, so that might help you debug the problem?

Rashid

09/25/2023, 9:43 AM

if i check line number 35 it show this one :- classpath "com.palantir.gradle.dockergradle docker0.34.0"

Niels Doucet

task buildDockerLatest(type: docker)

<-- I think you have the type wrong here. You're trying to use the plugin's extension as the type for your task. The plugin itself uses the

Exec

task type in order to create docker images: https://github.com/palantir/gradle-docker/blob/0.34.0/src/main/groovy/com/palantir/gradle/docker/PalantirDockerPlugin.groovy#L69-L73

Niels Doucet

09/25/2023, 10:08 AM

you should probably read the plugin's readme (and especially go through the examples): https://github.com/palantir/gradle-docker/tree/0.34.0

Rashid

09/25/2023, 10:09 AM

let me check

Rashid

09/25/2023, 10:10 AM

i read this docs link

Vampire

This is what I use to build docker images: https://plugins.gradle.org/plugin/com.bmuschko.docker-remote-api 🙂

Don't use Kotlin DSL syntax in a Groovy DSL file. Actually, I strongly suggest using Kotlin DSL anyway. You immediately get type-safe build scripts, much better error messages when you mess up the syntax in many cases, and amazingly better IDE support if you use a decent IDE like IntelliJ IDEA. Also you should not use the legacy

apply(...)

anyway, but use the

plugins { ... }

block to apply plugins in almost all cases.

Vampire

09/25/2023, 4:47 PM

And you should really update that ancient Gradle version you are using 🙂

Rashid

09/25/2023, 4:47 PM

i use visual studio code

Vampire

09/25/2023, 4:47 PM

Well, that's not really an IDE, but a fancy text editor. 🙂

Rashid

09/25/2023, 4:48 PM

actually my company use gradle 4.5 i know its older version but its support to your application

Rashid

09/25/2023, 4:48 PM

ok let me install IntelliJ IDEA

Rashid

09/25/2023, 4:48 PM

so that why i have to use gradle 4.5

Vampire

09/25/2023, 4:49 PM

I did not understand the "why"

Vampire

09/25/2023, 4:49 PM

Btw: https://bmuschko.github.io/gradle-docker-plugin/current/user-guide/

This plugin requires Gradle >= 7.4.0 to work properly.

Rashid

09/25/2023, 4:49 PM

its not in my hand i have follow procedure of what company said

Rashid

09/25/2023, 4:50 PM

then i have to use palantir.gradle

Rashid

09/25/2023, 4:51 PM

when i execute this command ./gradlew buildDockerLatest it automatically start downloading gradle 4.5

Rashid

09/25/2023, 4:52 PM

we already using palantir.gradle to build docker image and its working in other application

Vampire

09/25/2023, 4:52 PM

If your company forces you to use an ancient version of a build tool that then also forces you to use ancient versions of plugins that are still compatible or abandoned plugins that are unmaintained, they should really reconsider their policies. Alone the developer and CI time they waste in only allowing that ancient Gradle version is enormous and costs them muuuch money.

Vampire

09/25/2023, 4:53 PM

But well, if it works for you, great 🙂 Just mentioned that bmuschko's plugin works much better for me. 🙂

Rashid

09/25/2023, 4:54 PM

no we use gradle past 4 years has developer has to work on supporting gradle latest version in code

Vampire

09/25/2023, 4:58 PM

I did not get that sentence. But anyway, if you are bound to that Gradle version, you can maybe go back in history to find a vesrion of bmuschko's plugin that was compatible with it, or you can continue using palatir, whatever suits you best. 🙂

Rashid

09/25/2023, 4:59 PM

Vampire

09/25/2023, 4:59 PM

Niels most probably already told you what the actual problem was 🙂

Rashid

09/25/2023, 4:59 PM

yeah

Rashid

09/27/2023, 10:11 AM

Hi, I made changes in build.gradle file as got help from developer but when i execute gradle i got below error Error

Copy code

./gradlew docker

FAILURE: Build failed with an exception.

* What went wrong:

here is new build.gradle file

Copy code

buildscript {
    // ext {
    //     springBootVersion = SPRING_BOOT_VERSION
    //}
    repositories {
        mavenCentral()
        maven {
            url "<https://plugins.gradle.org/m2/>"
//            url '<https://repo.spring.io/libs-milestone>'
        }
    }
    dependencies {
        // classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        //       classpath('se.transmode.gradle:gradle-docker:1.2')
        classpath "com.palantir.gradle.docker:gradle-docker:0.34.0"
    }
}
apply plugin: 'com.palantir.docker'
//apply plugin: 'docker'

//tasks.named("dockerPrepare").configure { dependsOn("bootJar") }

    docker {

//        tasks.docker.dependsOn('build')

    }

task wrapper (type:Wrapper) {
    gradleVersion = '4.5' //we want gradle 2.10 to run this project
}

Vampire

That's not a Gradle question, but a question for the Palantir plugin actually. It tries to invoke the command

docker

and expectes that you have it in your

PATH

which you do not.
