Setting up pitest with JUnit5 without keeping any versions in build.gradle

[jan-gebauer]

Hi,

our usecase is that we would like to keep all version numbers out of our build.gradle files. Normally, we do this by using init.d in our .gradle folder. This worked well for version of the plugin itself but not so much for the junit5PluginVersion. It also works reasonably well for the other settings, such as mutationThreshold.

In init.d we have a file called pitest.init.gradle that looks like this

allprojects {
  afterEvaluate { project -> 
    project.plugins.withId("info.soildsoft.pitest") {
      junit5PluginVersion = '1.2.1'
      mutationThreshold = 65
      // other settings
    }
  }
}

The pitest version is set elsewhere. The presented code does not work and it is as if we didn't set the junit5PluginVersion at all. Are we doing something wrong? Is there a way to do this?

I noticed that there was a discussion about it but nothing seemed conclusive.

Maybe instead of 1.2.1 you could refer to some dynamic global variable ext.xxx which should be set before the afterEvaluate closure is effectively called?

Could you paste a link to it?

You could also try to approach this case from the other side and mimic the helper logic in your init.d, effectively adding org.pitest:pitest-junit5-plugin on your own (in the pitest configuration).

gradle-pitest-plugin/src/main/groovy/info/solidsoft/gradle/pitest/PitestPlugin.groovy

Lines 235 to 246 in 92cc7a8

	private void addPitJUnit5PluginIfRequested(Configuration pitestConfiguration) {
	pitestConfiguration.withDependencies { dependencies ->
	if (extension.junit5PluginVersion.isPresent()) {
	if (extension.testPlugin.isPresent() && extension.testPlugin.get() != PITEST_JUNIT5_PLUGIN_NAME) {
	log.warn("Specified 'junit5PluginVersion', but other plugin is configured in 'testPlugin' for PIT: '${extension.testPlugin.get()}'")
	}
	String junit5PluginDependencyAsString = "org.pitest:pitest-junit5-plugin:${extension.junit5PluginVersion.get()}"
	log.info("Adding JUnit 5 plugin for PIT as dependency: ${junit5PluginDependencyAsString}")
	dependencies.add(project.dependencies.create(junit5PluginDependencyAsString))
	}
	}

Hi, we ended up going with setting the version through the ext variable, thank you!

The discussion is here, I believe: #334

This issue can be closed, by the way.
