Compiling with current JDK throws error

[nickbe]

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.5.1:compile (java-compile) on project lavagna: Compilation failure [ERROR] X:\Workspace\GitHub-Systeme\lavagna\src\main\java\io\lavagna\service\ProjectService.java:[37,8] cannot access java.lang.Object [ERROR] bad class file: /modules/java.base/java/lang/Object.class [ERROR] class file has wrong version 58.0, should be 53.0 [ERROR] Please remove or make sure it appears in the correct subdirectory of the classpath.

So the question is exactly which JDK version was used to compile the project?

hi @nickbe ,

using sdkman, I'm using the following version:

$ sdk list java ... 8.0.242 | open | installed | 8.0.242-open

[nickbe]

Seems that this version for windows is not available for download anymore. Also from the Oracle site: https://www.oracle.com/java/technologies/javase/javase8-archive-downloads.html, i cannot locate any version number that seems to be the same.

@nickbe , you can download from:

• https://adoptopenjdk.net/releases.html
• https://developers.redhat.com/products/openjdk/download
• https://www.azul.com/downloads/zulu-community/?architecture=x86-64-bit&package=jdk-fx

Success 😁 Thanks a lot !
