Most of our Eclipse projects have multiple source folders, for example:
When you right-click on a class and
No.
Unless you change the plugin code, the default source folder is always the same as that containing the class you right clicked on (not necessarily the first source folder listed). I agree, it would be nice to be able to change it!
I use moreUnit, an Eclipse plugin to assist writing unit tests. Among other features, it lets you configure the default source folder of tests.
Now you can use my fast code eclipse plug-in. With this plug-in you can configure the test path to be src/test/java
only once. It also has a jump to the unit test feature. It is available at : http://fast-code.sourceforge.net/.
