Gradle · Kalm

Plugin ID: dev.kalm.language. The repository pins Gradle 9.6.1 with a checksummed wrapper. Install the Maven reactor first; the development compiler is resolved from Maven Local.

plugins { java; id("dev.kalm.language") }
repositories { mavenLocal(); mavenCentral() }
dependencies { implementation("dev.kalm:kalm-stdlib:0.1.0-SNAPSHOT") }
java { toolchain.languageVersion.set(JavaLanguageVersion.of(25)) }

kalm {
    mainSourceDirectory.set(layout.projectDirectory.dir("src/main/kalm"))
    testSourceDirectory.set(layout.projectDirectory.dir("src/test/kalm"))
    release.set(25)

    includes.set(listOf("**/*.kalm"))
    excludes.set(listOf("**/scratch/**"))
    compilerArguments.set(listOf("-Xlint:all"))
}

The plugin inherits the Java toolchain language version, vendor and implementation and defaults it to 25 when unspecified. Kalm runs in a separate compiler process on that JDK; the plugin itself uses Java 17 bytecode. Java compile release follows kalm.release unless explicitly configured in the host build. Releases below 25 fail.

Tasks

Task	Responsibility
`compileKalm`	Main joint signature analysis and Java generation
`compileJava`	Normal Gradle compilation of handwritten and generated main Java
`compileTestKalm`	Test generation against compiled main classes
`compileTestJava`	Normal compilation of handwritten and generated test Java
`testKalm`	Kalm tests, XML and HTML reports; prerequisite of `test`
`writeKalmProject`	Resolved workspace roots/classpath for the language server

Generation tasks declare source files, handwritten Java signatures, classpaths, compiler options and the launcher as inputs. Outputs live under build/generated/sources/kalm/main and test. Unchanged inputs skip generation; deleted sources remove stale generated files. Gradle's Java compiler maintains class outputs.

Reports: build/test-results/kalm/TEST-kalm.xml and build/reports/tests/kalm/index.html. Kalm tests run even when there are no JUnit tests. Failed checks fail test/check.
