# A green `test` task does not prove tests ran (see AGENTS.md), so this always
# prints tests/failures/errors per suite and dumps failure messages.
#
# A repository-wide lock serializes Gradle/test runs. Without it, an editor or
# another agent can delete build/test-results while this process is writing JUnit
# XML, producing EOFException or a missing in-progress-results bin.
#
# A `--tests` filter STICKS: Gradle reuses the configuration cache entry from the
# previous run, so a later unfiltered `./jaitest` silently re-runs just that one
# class and reports OK. Unfiltered runs therefore disable the configuration cache,
# which is the only reliable way to get the whole suite back.
#
# Usage: ./jaitest [gradle args...]      e.g. ./jaitest --tests '*Lexer*'
