Buildship problem with sub project after updating gradle wrapper from 7.2 to 8.9

After updating gradle wrapper from 7.2 to 8.9 buildship reports a problem in one of the subprojects

Synchronize Gradle projects with workspace failed due to an unexpected error.

Java Model Exception: Error in Java Model (code 964): Cannot nest ‘com.exoknox.fdm.shared/src/main/resources/com/exoknox/fdm/shared/util’ inside ‘com.exoknox.fdm.shared/src/main/resources’. To enable the nesting exclude ‘com/’ from ‘com.exoknox.fdm.shared/src/main/resources’

I’m using Buildship: Eclipse Plug-ins for Gradle 3.1.9.v20240116-1515

It is very inconvenient as it looks like the Project and external dependencies are not updated correctly.

Below you see the error from the log.

Regards
Marcel

Can you provide a minimal reproducible example?

Hope this helps.

Hi @MarcelRueedi

The gradle-git-properties plugin configures a second source folder src/main/resources/com/karakun/shared/util to the existing folder src/main/resources:

This is probably not intended an cannot handled by Eclipse:

Cannot nest ‘com.karakun.shared/src/main/resources/com/karakun/shared/util’ inside ‘com.karakun.shared/src/main/resources’.

From the description of the plugin:

// Customize file name (could be a file name or a relative file path below gitPropertiesResourceDir dir)
gitPropertiesName = "my-git-file.properties"

Using gitPropertiesName instead of gitPropertiesResourceDir no additional folder will be introduced:

gitProperties {
    // gitPropertiesResourceDir = file("${sourceSets.main.resources.srcDirs[0]}/com/karakun/shared/util")
    gitPropertiesName = "com/karakun/shared/util/git.properties"

    // [...]
}

Hi @oleosterhagen
Thanks for your help. As we need the file to be in the resources directory the solution is actually this.

gitPropertiesResourceDir = file("${sourceSets.main.resources.srcDirs[0]}")
gitPropertiesName = "/com/karakun/shared/util/git.properties"

Unfortunately - this seems only working on windows
linux/macs get
Execution failed for task ‘:com.exoknox.fdm.shared:generateGitProperties’. org.gradle.api.UncheckedIOException: Failed to create parent directory ‘/com’ when creating directory ‘/com/exoknox/fdm/shared/util’

my bad with

gitPropertiesName = "com/karakun/shared/util/git.properties"

its working
