9 months ago I'm having the same issue, adding relocate 'com.google.common', 'at.shadow.com.google.common' is causing build failure with java.lang.IllegalArgumentException: Unsupported class file major version 63.
This project is running on Java 11 (like @cnglen), cannot find any indication that Java 19(63) is being used.
@cnglen were you able to successfully fix this by using Shadow 8? Upgrading to Grade-8 is going to take a bit of work in my project and would like to avoid it if it didn't fix for you.

9 months ago Hey, i have the same issue when using shadow group: 'io.vertx', name: 'vertx-web', version: '4.4.2',
with shadow group: 'io.vertx', name: 'vertx-web', version: '4.4.1' it works (but thats an older version)
Note: all newer versions of vertx produce the same error

8 months ago Hi, did anyone managed to find a workaround for this issue? A lot of newer library versions are 'multi release' versions, aka including in META-INF/versions java classes compiled for multiple JDK's, see https://openjdk.org/jeps/238

8 months ago I tried compiling it with JDK8, but it also produced the META-INF/versions/ folder.

7 months ago I too am running into the same issue when I use a relocate in the shadow plugin, anyone found out a workaround to get over this issue?
What went wrong: Execution failed for task ':shadowJar'. Unsupported class file major version 63

7 months ago The problem went away when using "com.github.johnrengelman.shadow" version "8.1.1" instead of version 7

5 months ago The problem went away when using "com.github.johnrengelman.shadow" version "8.1.1" instead of version 7
The problem is still present with 8.1.1 version on my end.

5 months ago Yes I think the problem is still present and as @cornelcreanga points out more and more libraries are using the multi-release style jar files https://openjdk.org/jeps/238.
So if you are running a lesser JDK such as JDK17 and you happen to use one of these multi-release style jars that has class files for JDK17 and JDK19 you see this exception for the JDK19 class files:
java.lang.IllegalArgumentException: Unsupported class file major version 63The JVM and I presume ASM simply doesn't know what do with a higher version class file.
Does the filter / exclusion logic in the Shadow jar work before ASM kicks in? Seems like it doesn't given what we are hearing from reports.
I ran into this issue myself with the latest jackson-core library and filed an issue there originally: https://github.com/FasterXML/jackson-core/issues/1210

4 months ago Shadow 8.1.1 works well on Gradle 8 and Java 19, check https://github.com/Goooler/StringResExporter/pull/29.
@rmatec If it does not work for you, please provide me with a minimum reproducer.
Please check the User Guide before submitting "how do I do 'x'?" questions!
