Gradle / Rerun Tests Even If Up To Date

Rerun Tests Even If Up To Date

Forces a rerun of Gradle tests, ignoring timestamps.

$
Terminal
gradle test --rerun

When To Use

When debugging intermittent issues that may not appear on stable runs, requiring full test execution regardless of up-to-date status.

Pro Tip

Be aware that this may lead to longer build times due to unnecessary test re-execution; use judiciously in CI pipelines.

Common pitfalls

Error: No tests are defined in the project.

FAILURE: Test execution failed due to environment issues.

Solution: Investigate environmental problems such as missing dependencies or Java configuration.

Error: Unsupported command option specified.
