Thx for a PR. We just went through full overhaul of a gradle build so location of these versions changed. I'll handle this myself a bit later.

@jvalkeal Hi, I see you are trying to bump gradle to the latest one. I want to help a little 🙂

To avoid all gradle deprecation warnings you need:

Pushed to this pull request

• new versions of gradle enterprise and ge conventions, see 6f2b5fd
• java {} block for the sourceCompatibility line, see eb71d7b

What should be done:

1. Replace usage of "JavaPluginConvention.class" in RootPlugin.java with this:

SourceSetContainer sourceSets = project.getExtensions().getByType(JavaPluginExtension.class).getSourceSets();
SourceSet mainSourceSet = sourceSets.getByName(SourceSet.MAIN_SOURCE_SET_NAME);

p.s. now it fails to build, as java plugin is not recognized in the buildSrc project, something wrong with dependencies

2. Junit must be called with testRuntimeOnly according to Gradle Docs:
   testRuntimeOnly("org.junit.platform:junit-platform-launcher")

3. If you'll use "spring java format" plugin (other spring projects have it), use latest 0.0.41
