Hello Gradle folks
I’m a new Gradle user.
To learn about Gradle, I followed the well-written tutorial in Building Java Applications Sample.
Then I configured Gradle in an existing Java application. Many Gradle tasks run, but they don’t run the unit tests, even after ./gradlew clean or when I modify the unit test code.
To debug, I’ve tried running ./gradlew clean test --info --tests RewriteAttributeTagsTest where RewriteAttributeTagsTest is a unit test I wrote, and then modifying the unit test. It does compile, because if it contains garbage the compile dies with an appropriate error. But it doesn’t run the tests, because if I create a test that fails that doesn’t get reported. Unfortunately the output of --info does not enlighten me.
Here are the key files:
