在上面我添加了 pom.xml 文件和错误消息。我使用 java 1.8 和 maven 3.6.1 版本。我已将 JAVA_HOME 设置为 1.8 。项目构建失败，出现以下错误。任何人都可以描述如何解决这个问题。这将会很有帮助。提前致谢。

Answer 1

所有的点都表明你的 JDK 1.8 中有问题。 (它正在使用 JDK7 或更早版本编译)

分别使用 JDK 7 和 8 进行简单测试:

(查看版本 7 中的输出:javac:无效标志:-parameters)

$ javac -version
javac 1.7.0_201
$ javac -parameters
javac: invalid flag: -parameters
Usage: javac <options> <source files>
use -help for a list of possible options


$ javac -version
javac 1.8.0_191
$ javac -parameters
javac: no source files
Usage: javac <options> <source files>
use -help for a list of possible options
