Exclude Certain Packages From Export (Java) [message #631575]

Hello, world!

I just started using Eclipse with Java yesterday, and everything in going nicely so far.

I'd like to export my project to an executable .jar, but I don't want to include my jUnit tests. How can I exclude them from the export? I tried to go Project > Properties > Build Path > Export tab, but I can't check/un-check the packages I want/don't want.

Thanks in advance!

Simply uncheck when doing the JAR Export. If you plan to repeat the
export you can store it in a JAR description.

Thanks for the reply. What I was trying to say was, I can't uncheck any source folders. They're already unchecked. Here's a screenshot to show you what I mean.

Jonah,

You don't want to "uncheck" anything in Build Path (per your illustration).

To create a JAR, you right-click on the project and choose Export... (as
you started to do). But, when you reach the JAR Export dialog, you
uncheck what is probably your test subdirectory.*

If you like, peruse this discussion here:

http://www.javahotchocolate.com/tutorials/jars.html

* Now, if you didn't put your JUnit tests under a separate Source
Folder, parallel to src, then you should do that (it's a "best
practice") and that might be why you find it impossible to exclude them.

Come back if this isn't helpful,

When exporting a .JAR file, I do see the ability to exclude files/directories. But in this case, I'm exporting a runnable .Jar file, and it gives me no such option.

If what I have setup now is not best practice, please tell me how to change it to best practice. This is the first time I've worked with Java; I have pretty extensive experience with PHP.

(Don't bump in this forum. Your question will always be answered as soon
as someone sees it who can answer it.)

Here's how to set up JUnit tests.

1) Right-click the project and choose New -> Source Folder. Name it "test".

2) Right-click test, then choose New -> Package. Name the package the
same as the package under src folder that contains the code your JUnit
class will test.

3) Create your JUnit test class under this package. If you've already
created a JUnit test under src folder, open both src and test, then drag
the JUnit test from under src to under test.

Okay, sorry.

I followed your instructions. I now have:

src/
___packagename [package] /
______[code files]
test/
___packagename [package] /
______[test files]

But I still haven't found a way to exclude the jUnit test files from the runnable jar export. Until this problem is solved, I can just do it manually from the terminal. But, this really should work. Any ideas?

Thanks

Use File > Export... > JAR file

Thanks Dani, but I'm trying to export the runnable jar without jUnit or my test classes.

Right, and as you notice this doesn't work unless you split the tests
into a separate project or use the way I suggested.

Yes, I figured out how to keep the test code out of a normal .jar export. Are you saying that the .jar export and the runnable .jar export are the same thing? Thanks for your help so far...

Edit: this export option:

The distinction between the two is that the runnable JAR has a class
containing a main() method.

If you wish to create a JAR containing your JUnit test code that is
runnable, there is a bit more work to it, see note under
http://www.javahotchocolate.com/tutorials/jars.html#runnable jar

Yes. My program has a main() method. What I want to do is to make a distribution runnable .jar without the test code in it. Thanks.

What I think Dani and Russell are trying to tell you is that you need to
do Export > JAR and then specify a manifest file that makes it runnable
(Google "runnable jar manifest" for details on the contents of the
manifest file).
It might be easiest to use the Runnnable JAR export wizard to generate
the JAR with manifest and then copy it's manifest file into your project
so you can use it for the "regular" JAR export where you exclude test code.

Hope this helps,
Eric

Great! That works, I suppose I didn't understand. I wonder why the export runnable jar doesn't give you the option to remove selected directories/files. I copied the manifest into my project directory, so now I just select "Use existing manifest from workspace" when exporting a normal jar.

Thanks a lot!

I had the same issue, and here's the better solution. You don't have to use normal jar export, and you can fine control which files to include/exclude. See this:
