问题描述
当我在多模块的其中一个模块上运行 mvn test 时，出现以下错误:
When I run mvn test on one of the modules of a multi-module, I get the following error:
java.lang.IllegalAccessError: class org.junit.platform.launcher.core.LauncherFactory (in unnamed module @0x76329302) cannot access class org.junit.platform.commons.util.Preconditions (in module org.junit.platform.commons) because module org.junit.platform.commons does not export org.junit.platform.commons.util to unnamed module @0x76329302

我还有其他几个模块与这个模块有类似的 pom.xml 文件.他们运行得很好.
I have several other modules that have similar pom.xml files as this module. They run just fine.
我尝试了许多在线建议的方法，但都没有成功.还有什么建议吗?
I'v tried a number of things suggested online with no success. Any more suggestions?
推荐答案
我认为您不需要使用 JPMS.我们在未来版本中进行了修复，请参阅 Jira.请使用禁用 JPMS 的解决方法
I think you do not need to use JPMS. We have a fix in the future version, see Jira.
Pls use the workaround <useModulePath>false</useModulePath> which disables JPMS.
