Cannot build. Relies on environment dependencies for Heyler10gbData

[AnonymousJavaDev]

a simple workflow like:

git clone https://github.com/tag-bio/umap-java.git
cd umap-java
mvn install

does not work. It is failing on the tests in the tagbio.umap.Heyler10gbData class.

It appears that it is expecting the user to set three environment variables:
...
super( java.lang.System.getenv("TAGBIO_HEYLERTEST_10GB"));
...
super( java.lang.System.getenv("TAGBIO_HEYLERTEST_20GB"));
...
super( java.lang.System.getenv("TAGBIO_HEYLERTEST_30GB"));

With no description of what those are supposed to do.

Commenting out this file entirely builds as expected... Perhaps this should be someone's personal test, not a global test?

The quick one-liner fix for this it to just add an @Ignore annotation on the test, like this

@org.junit.Ignore
public class HeylerTest extends TestCase {
  ...
}

You can still run such tests on demand from inside an IDE (at least in IntelliJ).

Perhaps you don't even need real data for this and can just generate a lot of pseudorandom data (which can still be done with a fixed seed to keep it repeatable) instead of loading it from a file? The way this test is written it doesn't actually verify anything, it just prints out how long it takes to run.

Thanks for that. This is still a problem in 2026. The code should be updated to simply exclude this test..

Ok, I've added the @org.junit.Ignore as described above.
