Empty git.properties is generated in submodules when injectAllReactorProjects=true starting from 8.0.0

Describe the bug (required)

When running git-commit-id-plugin on a multi-module maven project with a parent pom and injectAllReactorProjects set to true, all generated git.properties in submodules will end up with no content.

This bug affects versions 8.0.0+ of plugin, version 7.0.0 is the latest not affected one.

Tell us about the Plugin version used (required)

7.0.0, 8.0.2, 9.0.0

Tell us about the Maven version used (required)

Apache Maven 3.9.6 (bc0240f3c744dd6b6ec2920b3cd08dcc295161ae)
Maven home: /home/john.doe/.sdkman/candidates/maven/current
Java version: 17.0.11, vendor: BellSoft, runtime: /home/john.doe/.sdkman/candidates/java/17.0.11-librca
Default locale: en, platform encoding: UTF-8
OS name: "linux", version: "5.15.146.1-microsoft-standard-wsl2", arch: "amd64", family: "unix"

Steps to Reproduce (required)

Clone repository

Run maven initialize and check contents of generated git.properties files

mvn clean initialize

# non-empty diff as module1's file only contains header comment
diff -u target/classes/git.properties module1/target/classes/git.properties

Re-run with version 7.0.0 of plugin

mvn clean initialize -Dgit-commit-id-maven-plugin.version=7.0.0

# no differences between the files
diff -u target/classes/git.properties module1/target/classes/git.properties

Are there any stacktraces or any error messages? (required)

Ubuntu 22.04.4 LTS running inside WSL2 on Windows 11
Running same steps natively on Windows 11 reproduces same bug

Context (optional)

Looking through diff between 7.0.0 and 8.0.0 I think that this commit might be a culprit - ee43e57

the same issue after update from boot 3.2 to 3.3

Thanks for the detailed report! Likely related to #700

the same issue after update from boot 3.2 to 3.3

Spring Boot 3.2.x uses version 6.0.0 of this plugin, Spring Boot 3.3.0 switches to 8.0.2 of the plugin - spring-projects/spring-boot@53f8504

#754: Fix an issue where empty git.properties had been generated in s…

Thanks again for the reproducer and indeed the problem seems to be related to the changes done in ee43e57.

The issue seems to boil down to using:

properties = new Properties(contextProperties);

instead of the previous

properties = contextProperties;

The contextProperties are the properties that had been generated by a potential previous run and are essentially still correctly populated. The plugin will then essentially dump whatever was specified as the properties variable.

With a

properties = new Properties(contextProperties);

the properties seem essentially empty (contextProperties are still correctly populated):

[INFO] === GitCommitIdPlugin.runPlugin(#
#Tue Jul 02 17:45:23 CEST 2024
)

I must admit that is a bit of a strange behaviour and when reading the javadoc of the properties class I still wouldn't expect such behaviour. Defaults for me sound like they should be there, but secrectly disappear....

My fix from https://github.com/git-commit-id/git-commit-id-maven-plugin/pull/760/files would propose to run:

properties = new Properties();
properties.putAll(contextProperties);

which IMHO should also do the trick.

Thanks again for the report!

Merge pull request #760 from git-commit-id/754

Now released: https://github.com/git-commit-id/git-commit-id-maven-plugin/releases/tag/v9.0.1

@TheSnoozer

Thanks @TheSnoozer, can confirm that fix works:

mvn clean initialize -Dgit-commit-id-maven-plugin.version=9.0.1 && cat commons/target/classes/git.properties job/target/classes/git.properties | grep git.commit.id
