On the other hand, running the same command from main results in a successful build:

Observations from running com.google.cloud.storage.contrib.nio.testing.FakeStorageRpcTest in debugger mode in IntelliJ:
The test appears to be getting stuck at the call to getContent in

java-storage-nio/google-cloud-nio/src/test/java/com/google/cloud/storage/contrib/nio/testing/FakeStorageRpcTest.java

Line 51 in b3fb38d

String gen1read1 = new String(gen1.getContent(), StandardCharsets.UTF_8);

The method Blob#getContent then invokes StorageImpl#readAllBytes which is where the application is getting stuck for a long time.

Closing in favor of #1306
