How to exclude certain jars from copyDependencies task (duplicate handling strategy) about javapackager HOT 9 CLOSED

Hi @streamingdv!

I planned to split some JP features into several Maven plugins and Gradle tasks, so you can combine them, e.g, you can call CreateAppTask, run your stuff, and then call GenerateInstallerTask. I think this could bring a lot of possibilities. JP internal logic is able to do this:

Anyway, I'll try to reproduce your issue and find a simple solution or a workaround.

If you want to do some research by yourself, take a look into this:

This is the snipet of code which copies dependencies in Gradle.

Thanks, it works now with the provided Snapshot. :)
I hope this will make it into the next release.

Hi again!
I've managed to reproduce your issue:

C:\Users\fvarrui\GitHub\HelloWorldGradle>build\HelloWorldGradle\HelloWorldGradle.exe
Error occurred during initialization of boot layer
java.lang.module.FindException: Two versions of module javafx.graphics found in libs (javafx-graphics-22-win.jar and javafx-graphics-20.0.1-win.jar)

The problem is not about duplicated jars, but duplicated modules (javafx.graphics module is twice) ... what if you call your custom javafx.graphics.jar with the same name as the JAR which is being included by javafx-gradle-plugin ('javafx-graphics-22-win.jar), so it'll be ovewriten with your custom JavaFX jar. I've just released a SNAPSHOT version with DuplicatesStrategy=EXCLUDE when copying libraries to avoid this error: 1.7.6-20240421.230018-6 ... try it and give me some feedback, please.

Could not find io.github.fvarrui:javapackager:1.7.6-20240421.230018-6
Which maven repo should I include in my gradle script in order to use the snapshot?

from javapackager.

New snapshot released: 1.7.6-20240423.010107-7.

Now duplicatesStrategy=WARN by default, but you can set a different duplicates strategy to your PackageTask:

tasks.register('packageApplication', PackageTask) {
    // mandatory
    mainClass = 'com.grill.app.Launcher'
    // optional
    bundleJre = true
    generateInstaller = true
    administratorRequired = false
    copyDependencies = true
    [...]
    duplicatesStrategy = DuplicatesStrategy.[EXCLUDE|FAIL|INCLUDE|INHERIT|WARN]
}

and this should work too:

tasks.configureEach {
    if (it instanceof Copy || it instanceof Zip || it instanceof Tar || it instanceof PackageTask) {
        it.duplicatesStrategy = DuplicatesStrategy.EXCLUDE
    }
}
