Java 9的Maven编译问题
Java 9的Maven编译问题
提问于 2017-10-23 04:07:33
尝试使用JDK 9.0.1编译Maven项目时，我遇到了这种堆栈跟踪，但没有太多解释：

其他详细信息
编译器Maven3.5.0带有maven-
- -plugin 3.7.0
- 我只是在执行mvn全新安装
- 不幸的是，源代码不是开源的，所以我不能自由地分享它
- 目前还没有模块信息.java文件，我只是想用Java9
编译一个项目如果我把源代码级别留在1.8，代码就会编译，但是如果我把它指定为9<代码>H213<代码>F214，代码就会编译失败，出现上述异常

只需添加以下内容
<forceJavacCompilerUse>true</forceJavacCompilerUse>到你的maven编译器，在POM中构建插件，你会看到所有的javac错误！Source with more details
