Hello,

What makes a package be a package? When checking the sources of a projekt
in filesystem each package (that I see in the package explorer) is basicly
a folder in the filesystem. Currently I have the problem, that I've a
imported project where the source folders children are are handled as
folders and not as packages as they should. As a result the plugin is not
working :(

Any Ideas?

Jan,

If you look at the Properties... of a project, and look at the Java
Build Path's Source tab, you'll see that here you can specify which
folders acts as roots for packages.

available'

Jan,

It is even a Java project? I.e., is the little "J" in the upper right
corner? I'm not sure there's a way to convert a project to a Java
project once it exists. Best to create the right type of project and
then copy the rest into that...

Ed,

No there is no 'J' :(
I've created this project as java project on one machine. I shared it
using SVN and exportet it to another machine. Somehow I mus have missed
something important. It seems something defines a java project. And it
seems that I must have forgotten to share that 'thing'.

Thank you for your help Ed. It is allways impressive how fast you keep
answering questions and how anxious your are!

You might be able to just edit the .project file (use the navigator view
to see it) and add the Java nature:
<natures>
<nature>org.eclipse.pde.PluginNature</nature>
<nature>org.eclipse.jdt.core.javanature</nature>
</natures>

Just create a new Java project to see what the default java contents are.

Jan,

I faced a similar problem. I copied project from one system to another
using a shared folder. When i finished importing project onto the new
workspace, there was no package structure rather just a folder structure
was displayed in the package explorer.

To fix this i used the PDE Tools -> update classpath option by right
clicking on the project in package explorer. This solved it for me.

Jan,

Note the other comments about the .project file... It's important that
the .classpath and .project files are also checked into SVN. You can
unfilter .* resource so you'll see them in the navigator/explorer...

And in addition is important that the .settings folder is also checked
into SVN. That's the only way that the project is sure to look and act
the same on everyone's system.
