Change proejct type on the fly? [message #156597]

Can I change the type of a project after its creation? I believe it may
have something to do with associating new plug-ins (and natures!) with the
project. Not sure how to get this done though?

Specifically - when I check out a project from a CVS repository, a simple
project gets created. In order to compile the code (it's Java), it seems
the project needs to be of "Java type". How do I now change the project
type without losing the CVS functionalities (compare with latest version,
etc)?

Thanks in advance

- Open the ".project" file of you project. You might have to switch to
the Resources perspective to do that.
- Find the "natures" section. For a plain java project it should look
like this:
<natures>
<nature>org.eclipse.jdt.core.javanature</nature>
</natures>
- To attach a java builder, check the "buildSpec" section. It should
contain:
<buildCommand>
<name>org.eclipse.jdt.core.javabuilder</name>
<arguments>
</arguments>
</buildCommand>
- You also might have to patch or even create the ".classpath" file. Its
"classpath" section should at least contain:
<classpathentry kind="con"
path="org.eclipse.jdt.launching.JRE_CONTAINER"/>
- Depending on whether you have a "bin" directory you should have:
<classpathentry kind="output" path="bin"/>

But you should be able to resolve most of these issues during checkout.
When you checkout a project, that is not an Eclipse project, the "Check
out As..." dialog offers to "Checkout as project using the New Project
Wizard". Try that.

Hope that helps,
Chris

Not sure if you want to do it through a UI or programaticaly. Through a UI,
it is not possible (I believe there's a feature request somewhere in
bugzilla). Programaticaly, you need to set the description of the project
(see IProject.setDescription(...)).

If your project in the CVS repository was checked in without a .project
file, then when you check it out, just choose 'Check Out As...' and in the
New Project wizard choose 'Java project'.
Otherwise you can manually edit the .project file and add the following in
the projectdescription:
<buildSpec>
<buildCommand>
<name>org.eclipse.jdt.core.javabuilder</name>
<arguments>
</arguments>
</buildCommand>
</buildSpec>
<natures>
<nature>org.eclipse.jdt.core.javanature</nature>
</natures>
