Maven: could not find a problem with java.lang on OS X

Question

I get the following problem when I tried mvn clean install it is obvious that it cannot find the runtime jar, but what do I need to do?

error log:

Answer 1

I think I found the problem.

Apple changed rt.jar to classes.jar, which is located in.

/System/Library/Frameworks/JavaVM.framework/Versions/ <your_java_version> /Classes/classes.jar

I need to modify my pom.xml to show it the path to classes.jar.

Edit: in a project with a few bugs. Creating soft links to jar classes in the lib directory is much better.

 sudo ln -s ../../Classes/classes.jar ./rt.jar 

Well sudo , because writing as a result of the /usr/libexec/java_home , which is your java home directory, requires administrative privileges.

I am using Java 8 Azul ZuluFX on Lubuntu 18.0.4. I'm working on the project:

 mvn clean package 

but I get this error (simplified):

 [ERROR] Failure executing javac, but could not parse the error: [ERROR] [parsing started RegularFileObject[/home/marco/sources/tgtools.activiti.explorer/src/main/java/tgtools/activiti/explorer/config/Constants.java]] [ERROR] [parsing completed 13ms] [many others...] [ERROR] [search path for class files: /home/marco/.sdkman/candidates/java/8.0.212-zulu/jre/lib/rt.jar;[many others...] [ERROR] Fatal Error: Unable to find package java.lang in classpath or bootclasspath 

I checked and /home/marco/.sdkman/candidates/java/8.0.212-zulu/jre/lib/rt.jar exists, and it obviously contains java/lang folders and its classes inside.
