java.lang.ExceptionInInitializerError & java.lang.NoClassDefFoundError (Linux)

[TotallyMehis]

Running mvnd -v I get the following output:

Apache Maven Daemon (mvnd) 2.0.0-rc-1 linux-amd64 native client (39127a46697aa1f64d19b106f943a1a13c9f1637)
Terminal: org.jline.terminal.impl.PosixSysTerminal with pty org.jline.terminal.impl.jni.linux.LinuxNativePty
java.lang.ExceptionInInitializerError: null

Running the command again gives me:

Apache Maven Daemon (mvnd) 2.0.0-rc-1 linux-amd64 native client (39127a46697aa1f64d19b106f943a1a13c9f1637)

java.lang.NoClassDefFoundError: Could not initialize class org.mvndaemon.mvnd.nativ.CLibrary

JDK seems to start fine (mvnd --status):

I am using Fedora 41. JDK:

openjdk version "21.0.6" 2025-01-21 LTS
OpenJDK Runtime Environment Corretto-21.0.6.7.1 (build 21.0.6+7-LTS)
OpenJDK 64-Bit Server VM Corretto-21.0.6.7.1 (build 21.0.6+7-LTS, mixed mode, sharing)

Related to #872 ?

Yes, there was a LOT of related changes in mvn and mvnd (both master), and due these changes not yet ported to mvnd, you cannot build it currently. Soon will merge https://github.com/apache/maven-mvnd/pull/1253 that will "align" mvnd and mvn, and JLine3 stuff should be fully aligned.

Hi there.

I still get a NoClassDefFoundError with 2.0.0-rc-3:

I'm not very Linux savvy, but I was able to get mvnd to work by building it myself. Just had to install the static version of zlib.

Having this issue on Fedora 43 as well.
