             Summary: improve Reproducible Builds after Surefire 3.0.0-M5 release
                 Key: SUREFIRE-1802
                 URL: https://issues.apache.org/jira/browse/SUREFIRE-1802
             Project: Maven Surefire
          Issue Type: Improvement
    Affects Versions: 3.0.0-M5
            Reporter: Herve Boutemy


Surefire 3.0.0-M5 was released with build enhancements that sould make the build reproducible: results are good but not perfect

the good part: the release manager (Tibor) is able to rebuild on his local environment and get the full set of artifacts exactly as they are published to Central

the not perfect part: trying to reproduce independantly shows a few issues that are build with a little difference to the reference artifacts from Central

see [https://github.com/jvm-repo-rebuild/reproducible-central] for automated rebuild script, that when run on my own machine give followinf results: [https://github.com/jvm-repo-rebuild/reproducible-central/blob/master/content/org/apache/maven/surefire/surefire-shared-utils-3.0.0-M5.buildinfo.compare]
 * the build produces 45 artifacts exactly like reference in Central
 * 5 artifacts are not produced exactly like the reference in Central:
 ** surefire-shadefire-3.0.0-M5.jar
 ** maven-surefire-plugin-3.0.0-M5.jar
 ** maven-failsafe-plugin-3.0.0-M5.jar
 ** maven-surefire-plugin-3.0.0-M5-sources.jar
 ** maven-failsafe-plugin-3.0.0-M5-sources.jar

We need to investigate how to make the build more independant from the environment, discovering how the environment impacts
