[External] : Re: apps compilation fails on ubuntu 20.04

[Abhinay Agarwal]

The piece of code responsible for the exception is:

for (File f : configurations.compileClasspath.files) {
    // Have to rename the swt jar because it is some platform specific name but
    // for the sake of the IDEs we need to have a single stable name that works
    // on every platform
    copy {
        into libsDir
        from f.getParentFile()
        include "**/*swt*.jar"
        includeEmptyDirs = false
        rename ".*swt.*jar", "swt-debug\\.jar"
    }
}

>From the code snippet, it looks like Gradle is being very pro-active and complaining that this could end up with multiple jar files containing "swt" in their name and we need to provide a duplicate strategy for it.


We can either provide a duplicatesStrategy or update the above to the following:

copy {
    into libsDir
    from configurations.compileClasspath.files
    include "**/*swt*.jar"
    includeEmptyDirs = false
    rename ".*swt.*jar", "swt-debug\\.jar"
    // duplicatesStrategy = DuplicatesStrategy.WARN
}

Interesting. I wonder what it is about your environment that causes the duplicate, since we don't see the problem in our CI builds nor in the GitHub Actions builds. I presume you have done a clean build and still see it? It is possible that you have some SWT classes in your classpath or jlink'ed into your boot JDK?

Hi Kevin,

My local repository is up-to-date with the jfx repository.

The failure happens while trying to copy swt-debug.jar:

$ sh gradlew sdk
...
> Task :swt:classes FAILED

FAILURE: Build failed with an exception.

* Where:
Build file '/tmp/jfx/build.gradle' line: 2677

* What went wrong:
Execution failed for task ':swt:classes'.
> Entry swt-debug.jar is a duplicate but no duplicate handling strategy has been set. Please refer to https://docs.gradle.org/7.0.1/dsl/org.gradle.api.tasks.Copy.html#org.gradle.api.tasks.Copy:duplicatesStrategy<https://urldefense.com/v3/__https://docs.gradle.org/7.0.1/dsl/org.gradle.api.tasks.Copy.html*org.gradle.api.tasks.Copy:duplicatesStrategy__;Iw!!ACWV5N9M2RV99hQ!fkRdlKBh300gss2krEHXu3UBrH7WOoht8YhvBygI4oIQd5dXyA2dXSrcTpkY5GOP5IQU$> for details.

P.S. Adding a `duplicatesStrategy` to the copy task also helps with the issue.

I still need to catch up on my email, since I still have the original
question in my queue.

The answer to the original query is that there is a known bug with ant
1.10.7 [1] that will cause this error. You can either use ant 1.10.5
(which is the one we specify in build.properties) or use ant 1.10.8.

As for the gradle sdk problem, I've not seen any problems relating to
using gradle 7.0.1. Is your repo up to date? Specifically, you need the
following commit:

https://github.com/openjdk/jfx/commit/111bac4180a646662a81223bdbb56880789d5a90<https://urldefense.com/v3/__https://github.com/openjdk/jfx/commit/111bac4180a646662a81223bdbb56880789d5a90__;!!ACWV5N9M2RV99hQ!fkRdlKBh300gss2krEHXu3UBrH7WOoht8YhvBygI4oIQd5dXyA2dXSrcTpkY5KEBj0BS$>
