为什么我无法在travis或Circle CI环境上获得测试资源？

Question

I'm facing a very annoying issue while trying to run my project's junit tests inside a remote CI environment.

In my local machine with java 1.8.0_181 and maven 3.5.4 I don't have any problem.

I used to use the two ways bellow to get a test resource:

        String expected = Utils.readStream(new FileInputStream(
            "src/test/resources/testdata/fragment-subdir-absolute-path.txt"));

Using this I'm getting a file not found:

java.io.FileNotFoundException: fragment-subdir-absolute-path.txt (No such file or directory)

And with this:

        String expected = Utils.readStream(new FileInputStream(getClass()
            .getResource("/testdata/fragment-subdir-absolute-path.txt")
            .getPath()));

In this case I'm getting a NPE:

[ERROR] testFragmentFragmentHost Time elapsed: 0.03 s <<< ERROR! java.lang.NullPointerException at org.osgi.service.indexer.impl.IndexerUnitTest.assertFragmentMatch(IndexerUnitTest.java:58) at org.osgi.service.indexer.impl.IndexerUnitTest.assertFragmentMatch(IndexerUnitTest.java:71) at org.osgi.service.indexer.impl.IndexerUnitTest.testFragmentFragmentHost(IndexerUnitTest.java:205)

But anyone is working inside of the remote CIs. The file is not being found.

Well, embarrassingly, after many many hours, I found where the issue was... :)

The culprit was a copied .gitignore file that contained this:

# Package Files #
 target
 *.jar
 *.txt

Eclipse IDE adds a small interrogation icon on the uncommited files, a small repo icon to the committed ones and just remove the icon from the ignored ones. I just didn't pay attention to those ignored ones.

So, I changed that file to:

# Package Files #
target/*.jar
target/*.txt 

and the mysterious unit tests errors have gone.

thank all for the time...
