Incompatible with the shadow plugin/shadowDist #94
Description
The Gradle shadow plugin has the ability to create an equivalent distribution but using the shadowed dependencies: https://imperceptiblethoughts.com/shadow/application-plugin/#distributing-the-shadow-jar
This plugin seems to set the javaagent path specifically for the ApplicationPlugin's task, not any/all CreateStartScripts type tasks. It might be useful to add the same injection of the javaagent to the ShadowApplicationPlugin.SHADOW_SCRIPTS_TASK_NAME task so it can be used in conjunction with shadow.
Working around this by basically recreating what the plugin does:
distributions.named("shadow") {
contents.from(configurations.javaagent) { into("agent-libs") }
}
tasks.named<CreateStartScripts>(ShadowApplicationPlugin.SHADOW_SCRIPTS_TASK_NAME) {
inputs.files(configurations.javaagent)
defaultJvmOpts = listOf("-javaagent:COM_RYANDENS_JAVAAGENTS_PLACEHOLDER.jar").plus(defaultJvmArgs)
unixStartScriptGenerator = JavaagentAwareStartScriptGenerator(configurations.javaagent.map { it.files })
}Edit: the workaround is a bit more complicated as the script generated using the above isn't usable...instead I'm manually mapping the javaagent files to jvm opts and working around gradle/gradle#19795 with a pattern/replace. It's a bit ugly...
tasks.named<CreateStartScripts>(ShadowApplicationPlugin.SHADOW_SCRIPTS_TASK_NAME) {
defaultJvmOpts = configurations.javaagent.get().files.map { jar ->
"-javaagent:\$\\{APP_HOME\\}/agent-libs/${jar.name}"
}.plus(defaultJvmArgs)
// FIXME - Replace env var template in `DEFAULT_JVM_OPTS`
// Workaround for https://github.com/gradle/gradle/issues/19795
doLast {
val envVarRegex = "\\\\\\$\\\\\\\\\\{(\\w+)\\\\\\\\\\}".toRegex()
val startScript = outputs.files.single().listFiles { file -> file.name == rootProject.name }!!.single()
val contents = startScript.readLines().joinToString("\n") { line ->
if (line.startsWith("DEFAULT_JVM_OPTS")) line.replace(envVarRegex, "\\$$1") else line
}
startScript.writeText(contents)
}
}
