Run Eclipse with M2 Maven build ignores “Store method parameter names” definition

问题

My application uses reflection in order to extract parameters names for a specific method.

I need the names like they are written in my code (and not arg0, arg1...).

In order to achieve this I go to: Windows -> Preferences -> Java -> Compiler - and mark: "Store method parameter names".

(I use JDK1.8 with Eclipse Kepler)

Now, when I do something like:

method.getParameters()[0].getName() 

If I run my application with Debug Configuration = Java application --> it works fine!

BUT, if I run it with Debug Configuration = M2 Maven Build --> it doesn't work! it show the synthesize names (arg0, arg1...)

I need it to work via Maven Build, Any idea??

回答1:

Try to explicitly tell compiler that you want method parameter names to be preserved:

<plugin>
   <groupId>org.apache.maven.plugins</groupId>
   <artifactId>maven-compiler-plugin</artifactId>
   <version>3.1</version>
   <configuration>
      <source>1.8</source>
      <target>1.8</target>
      <compilerArgument>-g:vars</compilerArgument>
      <testCompilerArgument>-g:vars</testCompilerArgument>
   </configuration>
</plugin>
