Problem with getting absolute paths

[ajs6f]

BaseCommonTests features a method

    protected static String getResourcePath(final String path) {
        try {
            return new File(BaseCommonTests.class.getResource(path).toURI()).getAbsolutePath();
        } catch (final URISyntaxException ex) {
            throw new RuntimeException(ex);
        }
    }

This is really unstable and fails every time under Maven with:

Caused by: java.lang.IllegalArgumentException: URI is not hierarchical
	at java.io.File.<init>(File.java:418)
	at org.trellisldp.test.BaseCommonTests.getResourcePath(BaseCommonTests.java:104)
	at [somewhere that called getResourcePath]

presumably because BaseCommonTests.class.getResource(path).toURI() is indeed not returning an URI that can be used for a file. In fact, I think this might only work in Gradle.

I'm not sure what to do here: ideally, we would decouple fully from build mechanics for tests, because I'm trying to reuse tests for trellis-cassandra-app and this is blocking me. But I certainly don't want to build up a whole resource management machinery instead!

In similar situations in Maven, I've passed in a system property with the absolute build directory. I wouldn't claim that so doing is that much better.

Some more details: it looks like this works on Gradle because Gradle is finding the path of the copy of a file that has been placed in the bin/ directory, whereas Maven is looking inside the actual JAR that has been built out of resources. I'm going to send a PR for overriding the problematic method-- it's the best thing I can think of in the circumstances, but a more elegant option is almost a desideratum.
