How to make compiler ignore certain subprojects? [message #251975]

I work on a large Maven1-based project in Eclipse. We build the deployment
package on the command line. I don't use the build in Eclipse, except for
fixing syntax errors. When I'm working on the project, I only ever care
about a small handful of subprojects. I've tried to configure Eclipse so
that it will only compile the subprojects I care about, by setting the
"Exclude" property on each source directory that I don't care about, to
"*.java". Unfortunately, this doesn't seem to make a difference. It
continues to try to compile subprojects that I've tried to exclude.

Is there something else I have to do to make it not compile the
subprojects I don't care about?

When editing the Source Folder exclusions, use the Add Multiple...
button and you can select an entire branch of the source tree to exclude.

Hope this helps,

I'm afraid that doesn't help.

Each subproject has its own source tree. I'm trying to exclude the entire
source tree of several subprojects. In the source entry for a subproject,
I add "*.java" to the exclude list. This doesn't appear to make any
difference. When the project is rebuilt, it still tries to recompile
source files in that subproject. Using "Add Multiple" only allows me to
select multiple directories in the source tree for the subproject. With
this, I would select "com" and be done, but that's the same as "*.java",
which didn't make any difference.

Did you actually try it? Using com/ from the Add Multiple... dialog and
specifying *.java are NOT semantically the same. I'm pretty sure *.java
will only exclude .java files that are at the root of the source
location; that is not a recursive or "deep" specification. To do it that
way you'd probably have to use something like **/*.java, as in the
examples in the dialog.

Hope this helps,
Eric

No, I didn't try it, because I had no idea the expression was used like
that. If I had actually read the info in that dialog, I would have used
"**/*.java" as you describe and I would have never asked this question :) .

Thanks.
