I am testing graalvm espresso. $ java --version java 21.0.2 2024-01-16 LTS Java(TM) SE Runtime Environment Oracle GraalVM 21.0.2+13.1 (build 21.0.2+13-LTS-jvmci-23.1-b33) Espresso 64-Bit VM Oracle GraalVM 21.0.2+13.1 (build 21-espresso-24.2.0, mixed mode)
I created a vanilla java program, which can be compiled and ran without a problem. However, when attempting to manage the project using maven (v.3.9.11), mvn throws An exception occurred while executing the Java class. Unsupported major.minor version 68.0. I know its version mismatched error. So I add related fields with version 24 such as maven.compiler.source, maven.compiler.target, source, target to pom.xml as below. But the problem remains. What's the correct fields or version value to specify for pinning the jdk source and target version? Or anything that I also need to configure or miss?
