java - Maven 找不到 java.lang

Question

我Java 8 Azul ZuluFX在 Lubuntu 18.0.4 上使用。我在一个项目上运行：

mvn clean package

但我收到此错误（简化）：

[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

我检查并/home/marco/.sdkman/candidates/java/8.0.212-zulu/jre/lib/rt.jar存在，它显然包含java/lang文件夹及其内部的类。

我有Maven3.6.0
