Javaagent Packing

A gradle plugin for developing javaagent applications.

Why this plugin

Fast packing all dependencies

Used many dependencies? JavaagentPacking will pack all dependencies you used automatic.

Avoid classpath pollution

Using this plugin can avoid classpath pollution. Applications on AppClassLoader can't access classes of javaagent.

Configure simply

Just adding a bit code into build.groovy

javaagent {
    bootstrap = "org.example.myjavaagent.Launcher"
    ofSourceSet("main")
    applyTests = true
}

Using this plugin

Adding id("io.github.karlatemp.javaagent-packing") version "0.0.4" into your plugins

Configure

javaagent {
    // required.
    //      The launcher of javaagent
    //      Require `public static void premain(String, Instrumentation)` exists
    bootstrap = "org.example.myjavaagent.Launcher"
    // optional: Default: the main source set of project
    //      SourceSet of javaagent application
    //      See gradle document for more details.
    ofSourceSet("main")
    // optional: Default: "io.github.karlatemp.jap." + project.name
    //      The package of wrapper jar (the final built jar)
    packageName = "org.example.myjavaagent.wrapper"
    // optional: Default: jpl
    //      The custom protocol scheme of `Launcher.class.getProtectionDomain().getLocation()`
    urlProtocol = "jpl"
    // optional: Default false
    //      Add `-javaagent` into tests
    applyTests = false
}

// Configuration of directly bootstrap
// In build.gradle.kts, use
//      tasks.named<JavaExec>("launchJavaagent") {}
launchJavaagent {
    mainClass.set('org.example.myjavaagent.test.Main')
    // If `classpath` missing, use test source set default.
    // If `classpath` modified, javaagent-packing will not change it again.
