Grails-7 questions. currently when I run my app as executable war file I have to do this in my build.gradle:

bootWar {
    from('grails-app/views') {
        into 'WEB-INF/grails-app/views'
    }

}

I found this very likely could be either gson files or gsp files not compiled correctly. I now turned both gson and gsp view comileStatic to false(otherwise there will be tons of compilation errors) However, when i trace into the groovyPageResolvers, I found the precompiledGspMap property did not get injected correctly, So, the gspResolver has to use a ResourceResolver instead of precompiledGspMap to resolve the gsp views. That's why it need the source code for the gsp pages to get the view resolved. This is so far I found.

Do you have an example project we could look at your configuration? There's so many things that could go wrong here that I can't really help without an example

I will try to build one example. As my project is kind of big. I am starting with a new Grails 7 project try to re-produce this issue by adding more my production code into it. If I started simple project, everything works by far. It might take me some time to get this fully reproduced.

usually issues like this are caused by third party plugins or a misconfiguration.

Yes. I am pretty certain of that. As if I build a simple grails7 project it works fine. This is the working project with some basic plugins from Grails 7, (asset pipeline, db migration, spring security), I still did not add spring session and spring data(redis) yet. will work on it to find out. By now I found is that my precompiledGspMap is not being populated correctly, I just do not know why.

at first glance, I don't see anything that sticks out - but i'm not sure what dc_common is - assume it's your local plugin

yes. that's my own plugin.

did you do a clean / remove your build directories before you upgraded?

yes. very clean

try building with the args

--no-build-cache --rerun-tasks

Nah, it should not be. the only suspicious error now, I have to turn off all compileStatic for both gson and gsp. So I am thinking maybe that could be related.

not sure why that would impact it

Yes. they are. both under WEB-INF/classes. However, I am not sure if all of them are compiled correctly. because there are too many of them. I then wonder if some of the gsp or gson are not compiled, so the precompiledGspMap refused to load. That’s why it tried to look up the source code by using

grails-app/views/my_app/view

instead of the

/my_app/view

the compiler should error if it doens't compile

With compileStatic=false, it wont error out

oh, you mean the rendering of the page itself

yes

what were the compilation errors?

I can run the app correctly without any error if I do grails run-app in developement mode. I only get these errors when I use an executable war file.

i think run-app uses a special development mode to load the files incrementally

Yeah. I need to find that out

The simplest way to debug these is usually to start with a clean app from start.grails.org and then layer on your customizations. From the screeenshot listing the plugins I can see you are missing grails-layout, which is why the CSS is not styling the page.

the screen shot shows "layout" which is the name of thge plugin in the grails-layout package

I see, it looked so much the other scenario

We still haven't seen an example error

Will do

@jdaugherty @James Fredley I found some of spring beans, failed to start with autoConfiguration. I have to disabled them by adding them into the excluding list as below: Now two of my apps can at least start without any issues. Some of them I have to use a Groovy(Java) configuration to set it up(Like Redis)

autoconfigure:
    exclude:
      - org.springframework.boot.autoconfigure.security.oauth2.client.servlet.OAuth2ClientAutoConfiguration
      - org.springframework.boot.autoconfigure.security.servlet.SecurityFilterAutoConfiguration
      - org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration
      - org.springframework.boot.actuate.autoconfigure.security.servlet.ManagementWebSecurityAutoConfiguration
      - org.springframework.boot.autoconfigure.security.oauth2.resource.servlet.OAuth2ResourceServerAutoConfiguration
      - org.springframework.boot.autoconfigure.security.servlet.UserDetailsServiceAutoConfiguration
      - org.springframework.boot.autoconfigure.task.TaskExecutionAutoConfiguration
      - org.springframework.boot.autoconfigure.data.redis.RedisAutoConfiguration
      - org.springframework.boot.autoconfigure.reactor.netty.ReactorNettyAutoConfiguration
      - org.springframework.boot.autoconfigure.webflux.WebFluxAutoConfiguration
      - org.springframework.boot.autoconfigure.webflux.client.WebClientAutoConfiguration

I set up a break point at this file at 610, then I can figure out all the auto configuration failed beans then exclude them.

Please add this as an issue on https://github.com/apache/grails-core/issues

will do
