QuarkusIntegrationTest cannot locate build output directory if it contains special characters like #

[bdevreugd-vialis]

My project path contains '#' character, which gives me the following exception:

java.lang.IllegalStateException: The determined Quarkus build output 'C:\Workspace\%23git\test\service\test-service\target' is not a directory
	at io.quarkus.test.junit.QuarkusIntegrationTestExtension.determineBuildOutputDirectory(QuarkusIntegrationTestExtension.java:154)
	at io.quarkus.test.junit.QuarkusIntegrationTestExtension.readQuarkusArtifactProperties(QuarkusIntegrationTestExtension.java:112)
	at io.quarkus.test.junit.QuarkusIntegrationTestExtension.ensureStarted(QuarkusIntegrationTestExtension.java:79)
	at io.quarkus.test.junit.QuarkusIntegrationTestExtension.beforeAll(QuarkusIntegrationTestExtension.java:73)
        ...

The problem is:

quarkus/test-framework/junit5/src/main/java/io/quarkus/test/junit/IntegrationTestUtil.java

Line 277 in 13fb194

private static File determineBuildOutputDirectory(final URL url) {

Which uses url.getPath, which gives an URL-encoded path! This can be fixed by calling URLDecoder.decode(p, "UTF-8") before providing the path to the File constructor.
