Ant：如何编译包含源附件的jar

Question

How do I create a jar with Ant that includes the source attachment?

Maven does this, but I'm living maven-free since '03 (well, 2009, but it doesn't rhyme).

I can't see any options in the javac task which does this.

I tried including the source .java files in the fileset passed to the javac task, but this didn't work. When I try to view the source through something like Eclipse, I still get the 'no source attachment' display.

Any suggestions?

You need two things to make it work in Eclipse:

• Include the source files in the file set, so that each .java file exists in the same folder in the JAR as the corresponding .class file;
• In the <javac> task, add the following parameter: debug="on" . That way, you encode information into the .class files about the corresponding .java files that tools like Eclipse need in order to connect the two together.
