Clean-room replacement for Gradle's maven-publish + Vanniktech. Emits JAR + sources + javadoc + POM + Gradle Module Metadata to Maven Local, Maven Central, or any custom Maven repo — read from the de-facto community POM_* gradle.properties convention. Fixes gradle/gradle#20294 by default.

Applies the Spex testing conventions and adds Spex's filesystem fixtures (ScratchSpace, ClasspathFixture) to the consuming project's test suite, for tests that touch disk.

Applies the Spex testing conventions and adds Spex's Mockito wrappers (the Doubles facade) to the consuming project's test suite, for tests using mocks, spies, stubs, and verifications.

Adds Spex core and the spex JUnit Platform engine to the consuming project's test suite, configured against JUnit Jupiter. Requires that the consumer has applied a JVM plugin (java-library, java, or application) first.

Applies java-library and jacoco, configures the Java 25 toolchain, JaCoCo XML coverage reports with build/generated-source class exclusions, jar manifest Implementation-Title/Version, and javadoc Xdoclint:all,-html with -quiet. Reads optional GROUP and VERSION_NAME project properties when set.

Settings-plugin that applies the Foojay toolchain resolver so requested JDK versions auto-provision without Gradle's no-toolchain-repositories deprecation warning.

Opinionated CLI build for an Iluvatar Command. Applies software.visionary.java-base, adds software.visionary:commander as an api dependency, and registers a jlinkApp task that produces a self-contained jlink runtime image plus a launcher script.
