Getting Netbeans and Subversion to play together nicely with libraries?

I'm having a difficult time figuring out how to add a .jar/library to a Netbeans project in such a way that I can get it committed to the repository.

The typical way to add a library (per the Netbeans documents I've already gone through) ends up with it just being local to me. Anyone who checks out my project ends up missing my required library.

Inserting it manually and trying to work around Netbeans results in Netbeans hanging while trying to scan the project...

So, how can I tell Netbeans to pick up a jar as a library and include it in my project in such a way that Subversion will be able to handle it?

Answer 1

There are a couple ways to fix this.

A. When you define your Library, use a path to a common location. A location that's identical on everyone's machine--such as the location of a JAR installed with a third-party app into Program Files or /usr/local/ works well or a network drive.

Then, when they check-out the code, the path will still be correct and they do not have to define the Library on their Netbeans workspace.

B. Edit your project.properties file to use a relative path. Open your project.properties file and look for "libs.LIBRARY_NAME.classpath=...". That will be the "default" location used if the Library is not defined.

Change this to use a path relative to your project and store the jar files in your project. For example: libs.Log4J.classpath=lib/log4j.jar

Keep in mind that the Library definition in your Library Manager will override this value--so make sure you keep them in-sync (i.e. append a version number to the library name!).

C. Use Vincent's suggestion of using a build-system such as Maven. The Maven build-process will take care of downloading dependencies, etc. Netbeans has plugins for several popular build systems.

Answer 2

There is a new feature in NetBeans 6.5 (variable-based paths in projects) which should make this easier.

See http://wiki.netbeans.org/NewAndNoteWorthyNB65#section-NewAndNoteWorthyNB65-VariableBasedPathsInJ2SEJ2EEProjects for details. Note the screenshot includes variable references in the library customizer.

Not really an answer to your question but... generally you should not include these libraries in your subversion repository. There is usually no need to have them managed. What you might want is to set up a central repository similar to what happens with maven. If you use maven, you can create a local repository of libraries on a server accessible by the team. The dependencies on these libraries are entered in the pom.xml file and this is in the subversion repository. Now, as team members check out the code from subversion they all have access to the maven repository.

[I am looking for a reference to this right now. When I find it I'll edit this answer.]

Answer 4

I use NetBeans IDE 6.5.1 and the best solution I've found so far is to include the needed libraries from your local host and then change their paths to relative. After that you have to remove the libraries manually from the NetBeans file explorer, and then copy them from their OS location in your computer manually to the file explorer again. That way NetBeans detects the change and you can commit it to the repository.

Note: I Highly recommend to clean and build the project again after updating.

Answer 5

An easy way to pack up your lib/jars into your project so that subversion "just handles it" so you can grab it out with all the attached libraries ready to compile and go is to include them all under your project directory via the "shared libraries" option by managing the libraries folder.

When creating a new project you can specify "Use Dedicated Folder for Storing Libraries" and then use the suggested relative .\lib path. If you have an existing project, you can edit it's properties, Libraries Category, and Browse for a Libraries Folder. Again a first-time run will suggest .\lib and then offer to copy existing dependencies to that folder. These graphical actions should provide similar results to James Schek's 'B' answer.

Commit the project with the newly added libs in .\lib and you should be able to checkout and build from anywhere and know you'll have the same libs (at the same version) as you had when you last built and committed.

I don't know how long this feature has been in NetBeans. For more details see:

Answer 6

I ended up just downloading my own set and putting them on my local drive for this project. I setup my Netbeans to look there and warned the other guys what I did... Eventually, we'll have to do something a bit more scalable though... :-)

Answer 7

OK, the working solution that I've now moved to is to extract the class files out of the jars and dump them into the Source Packages area. Then it all gets committed to the repository and also avoids having to deal with handling a separate "lib" directory in the deployment phase.

This solution does everything I'm looking for, yet I feel real dirty about doing it this way. It just seems horribly broken and wrong... :-)
