无法执行目标org.apache.maven.plugins：maven-compiler-plugin等

Question

The project has only one package containing all the .java files.

When I run it using maven, it complains:

Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.5.1:compile (default-compile) on project wx.center: Compilation failure: Compilation failure:

A dozen of errors look like these:

[ERROR] C:\Users\...\wx\center\TokenJob.java:[57,53] ERROR: needs';'
[ERROR] C:\Users\...\wx\center\TokenJob.java:[88,10] ERROR: there is 'catch', but no 'try'
[ERROR] C:\Users\...\wx\center\TokenJob.java:[88,26] ERROR: needs')'
[ERROR] C:\Users\...\wx\center\TokenJob.java:[90,10] ERROR: there is 'finally', but no 'try'

I have checked the eclipse settings,

and

As you can see, I have assigned the "installed JRE" and it matches the jre used by compiler.

And I have used vim to check the coding of TokenJob.java file, it looks ok.

All "errors" are around TokenJob.java file, so I commented the whole class leaving only

public class TokenJob {}

Then odd things happen, some other java files ask me to import java file that is already located in the same package, which should not.

I tried to copy TokenJob out and back, the same. I tried the above operation several times, and the "import java file in the same package" happens at random references/places.

This is my pom:

        </plugins>
    </build>
</project>

All I want is getting the jar file using maven. Thanks!

我认为问题在于阴影插件，因此请仔细阅读https://maven.apache.org/plugins/maven-shade-plugin/替代解决方案可能是http://www.mkyong.com/maven/how-to -用jar创建一个jar文件/

Answer 2

尝试删除eclipse Markers和Problems选项卡中的所有内容，然后尝试构建项目。
