jUnit on eclipse Indigo

Question

I installed Eclipse IDE for JavaScript Web Developers, Version: Indigo Service Release 1 Build id: 20110916-0149, in 2011 and use it for java development now but can see no menu about jUnit when I right click on a java class. Actually jUnit appears nowhere in the menus.

After going around forums, I tried to install JDT, as I understood this is where jUnit is contained. But installation failed because of a conflict with something already installed...

Can you help please ?

This looks pretty odd. Some background:

The plugin "Java Development Tools Launching Support" doesn't like to have different versions of itself installed in Eclipse. Eclipse 3.7.2 comes with version 3.6.1.v20111006_r372.

It seems that you still have old versions from 3.5 and 3.6 installed. Did you upgrade from an old version to 3.7?

Problems like that are usually only solvable by installing Eclipse again. Deleting the plugin on the disk won't help because p2 remembers which plugins are installed and doesn't care whether the plugin still exists. You probably also can't delete the plugin because some other plugin will depend on it.

I did have a previous eclipse installation before Indigo. What version of eclipse is best to install from scratch if I want to use java/Perl/Javascript/HTML ? Thanks – Fred Sullet Oct 03 '13 at 12:22
If you install again, then the latest since it will be the one for which you can get support. – Aaron Digulla Oct 03 '13 at 13:36
Which Eclipse version do you recomment to install for my java/Perl/Javascript/HTML developments ? Thanks – Fred Sullet Oct 05 '13 at 11:05
Install Eclipse e4, J2EE version and then the Perl plugin via the Marketplace. – Aaron Digulla Oct 06 '13 at 17:40
Thanks. Will it override completely my current installation ? – Fred Sullet Oct 08 '13 at 15:30
No, you can install it in a new folder and keep the old one. You should **not** install the new version over the old one. – Aaron Digulla Oct 08 '13 at 15:35
