好的,这是一个奇怪的问题:我有一个使用一些 UTF-8 字符的 java 测试文件。当我用 Maven 编译它时,使用
mvn -Dfile.encoding=UTF-8 -Dproject.build.sourceEncoding=UTF-8 test
(因此设置感知平台编码和源文件编码,请参阅maven 平台编码)我得到类似的东西

当我编译文件时
javac path/to/file.java
我收到类似的错误:

6 errors
现在当我使用
javac -encoding UTF-8 path/to/file.java
相反,cannot find symbol
由于缺少依赖项,我得到了错误。所以我认为问题是javac
在编译测试时没有在 Maven 中使用 UTF-8 选项调用它(注意-sectionUsing 'UTF-8' encoding to copy filtered resources.
中的缺失方式compiler:testCompile
)。这个结论正确吗?我错过了什么吗?这是一个已知问题吗?我能做些什么吗?显然,我系统上的平台编码不是 UTF-8,但我目前无法更改。
