How to exclude folders on project import [message #1737924]

Thu, 14 July 2016 04:32

I was trying to setup a project import task where some subfolders should not be imported.

  <setupTask
      xsi:type="projects:ProjectsImportTask">
    <sourceLocator
        rootFolder="${ease.git.clone.core.location}">
      <excludedPath>${ease.git.clone.core.location/developers}</excludedPath>
    </sourceLocator>
  </setupTask>

I was also trying regexp as exclude pattern ".*developers.*, but whatever I enter, projects from those folders still get imported. While I could setup import tasks on subfolder level I would love to use the more general approach with exclude patterns. Could you explain how this works?

thanks
Christian

Hi Christian,

IIRC. the excludedPath must not be patterns, but rather paths *relative* to the rootFolder.

Cheers

Stumbled upon this thread when looking for a solution as I can't get this to work.My maven import task looks like:

<setupTask
    xsi:type="maven:MavenImportTask"
    projectNameTemplate="">
  <sourceLocator
      rootFolder="${git.clone.projects.location}"
      locateNestedProjects="true">
    <excludedPath>project1-ignore</excludedPath>
    <excludedPath>project2-ignore</excludedPath>
  </sourceLocator>
</setupTask>

but both projects are imported while being a direct subdirectory of the git.clone.projects.location. What would be the correct format?

Regards
Kurt

It looks okay. It's used by org.eclipse.oomph.resources.impl.ProjectFactoryImpl.isExcludedPath(BackendContainer, BackendContainer) It looks like this one from Equinox.setup:

<?xml version="1.0" encoding="UTF-8"?>
<resources:SourceLocator
    xmi:version="2.0"
    xmlns:xmi="http://www.omg.org/XMI"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:resources="http://www.eclipse.org/oomph/resources/1.0"
    xsi:schemaLocation="http://www.eclipse.org/oomph/resources/1.0 http://git.eclipse.org/c/oomph/org.eclipse.oomph.git/plain/setups/models/Resources.ecore"
    rootFolder="${git.clone.equinox.p2.location}">
  <excludedPath>org.eclipse.equinox.p2.releng.buckminster</excludedPath>
  <excludedPath>bundles/org.eclipse.equinox.p2.testserver</excludedPath>
</resources:SourceLocator>

Failing that, you could instead create predicates (such as one that matches any project that doesn't have ignore in the name)...

I highjack this, because I have a very similar issue. I want to exclude everything from a given subfolder and its children. None of the available filters are useful for that:

* Excluded Paths have to list individual projects
* NamePredicate has no path information
* LocationPredicate gives me headaches: It checks against the full filesystem path of the project, converting \ to / on windows. To match the full path, I need to use ${git.clone.project.location}, but that still contains \ characters. I dont know if there's a filter, so that I can replace \ by / in ${git.clone.project.location}. Otherwise I won't ever match anything.

Maybe there is still a way to do this?
Thanks,
Felix

This filter isn't particularly well described:

    registerFilter(new DocumentedStringFilter()
    {
      public String getName()
      {
        return "path";
      }

      @Override
      public String getDescription()
      {
        return "Extracts the path segments from a URI.";
      }

      public String filter(String value)
      {
        return value.replaceAll("\\\\", "/");
      }
    });

But it's clear that it just replaces \ with / in whatever the string happens to be, and given that a URI will generally not contain \, and that this is typically used with a file system path not a URI, the description is poor at best and arguably misleading.

So I fixed that via https://bugs.eclipse.org/bugs/show_bug.cgi?id=561720 and updated the wiki.

Okay thank you, this might work.

Have you tried the Excluded Paths on the Source Locator? This can specify a relative path (using /) that should be excluded.

I cannot use a pattern on excludedPaths, only full project paths. It would be good if excluded paths would be a pattern match instead.

I thought maybe they would all be under one folder in the repo so you could exclude that folder and everything under it. But given I don't know anything about your structure, I can't actually offer advice on the simplest approach to filter certain projects. Your question seems to imply there is some pattern to be recognized via the folder structure...

Well that is exactly the case. I have a folder, and I want to exclude everything under it. Turns out.. I used my/external/folder/. You suggest that this must work so I tried without the trailing / and yes, that works. I was sort of biased, since 2 others in this thread said: it doesnt work, and the paths in your example above with the equinox.setup look like project paths, not some subfolders, so yes.. look at that fool. Wouldnt "some/path" and "some/path/" be equivalent here? What I mean is, that maybe trailing segments could be removed when the check is performed, so that both cases would work and do the expected?

I think you are suggesting that in https://git.eclipse.org/c/oomph/org.eclipse.oomph.git/tree/plugins/org.eclipse.oomph.resources/src/org/eclipse/oomph/resources/impl/SourceLocatorImpl.java#n567 it should strip a trailing / just as it currently strips a leading / so that this methods works properly in either case and does not currently work properly (at all) when there is a trailing /:

https://git.eclipse.org/c/oomph/org.eclipse.oomph.git/tree/plugins/org.eclipse.oomph.resources/src/org/eclipse/oomph/resources/impl/SourceLocatorImpl.java#n622

Is that correct?

Please open a Bugzilla. You could even fix it yourself:

This is failing for me.

It looks like it should work.

Is there a way to debug the SourceLocatorImpl code?
If I could inspect doHandleProjects() I could see what the problem is.

One would generally need to set up a development environment:

https://www.eclipse.org/setups/installer/?url=http://git.eclipse.org/c/oomph/org.eclipse.oomph.git/plain/setups/configurations/OomphConfiguration.setup&show=true

And then launch a runtime workbench (there is a launcher called "IDE" available for that). And in there you can debug org.eclipse.oomph.setup.projects.impl.ProjectsImportTaskImpl.perform(SetupTaskContext).

Often what I do is use Navigate -> Open Setup -> Workspace in that self-hosted launch and copy the task I want to debug there; copy and paste works between IDEs even. Then you can use Help -> Perform Setup Tasks to kick that task off to debug it. And if there are bugs you could contribute the fix for it...
