It seems working http://fusion2/ci/kokoro/prod:cloud-devrel%2Fclient-libraries%2Fjava%2Fjava-bigtable%2Fpresubmit%2Fintegration/activity/49a23571-fcaf-4ba6-94fb-779c61c956fc/log

Let's intentionally break the build by injecting wrong value.

It worked. http://fusion2/ci/kokoro/prod:cloud-devrel%2Fclient-libraries%2Fjava%2Fjava-bigtable%2Fpresubmit%2Fintegration/activity/8dc916e0-c486-4311-ae39-dbff143e52a2/log

}
env_vars {

The behavior seems to pick the last one.

It unexpectedly succeeded:

env_vars {
  key: "GOOGLE_CLOUD_PROJECT"
  value: "no-such-project-value2"
}
env_vars {
  key: "INTEGRATION_TEST_ARGS"
  value: "-P bigtable-emulator-it,bigtable-prod-it,bigtable-prod-batch-it -Dbigtable.project=gcloud-devel -Dbigtable.instance=google-cloud-bigtable -Dbigtable.table=integration-tests -Dbigtable.kms_key_name=projects/gcloud-devel/locations/us-east1/keyRings/cmek-test-key-ring/cryptoKeys/cmek-test-key -Dbigtable.wait-for-cmek-key-status=true"
}

Maybe -Dbigtable.project=gcloud-devel supercedes?
