[hibernate-dev] [OGM] Build time

My machine is in a poor state. But still, the default mvn install took more than 7 minutes. For info the minimal build takes 3:20 (4:30 with the integration tests). We have added a few mechanisms over time on OGM: * modules depending on an external DB are skipped if SOMEDB_HOSTNAME is not set * skipDocs which skips documentation and JavaDocs (JavaDocs take a lot of time on my machine) * skipITs which skips the integration tests * skipDistro which skips the distribution While each individual mechanism serves a purpose, it ends up serving everyone badly. Minimalarians complain about the myriad of flags to write each time. Safarians complain that if they forget COUCHDB_HOSTNAME, the distribution will simply not contain it. I think there are four main use cases 1. run the test suite for one specific db + rebuild core as things might have changed 2. run the minimal test suite to make sure things compile and work 3. run a full test on every backend and build the distribution for a release 4. other cases I suspect the % of time per use case is as follow (your mileage may vary): 1. 45% 2. 45% 3. 1% 4. 9% But when you are in case 3. you absolutely must be sure everything run and no module is skipped. Here is a proposal a. Provide a -Dminimal flag to run in case 1. b. Provide a -Dcomplete flag to run in case 3. c. Provide a script to do 2. I suspect case 2. can only be done with a custom script or by moving to Gradle. For various reasons, I don't want us to move to Gradle at this stage. Everyone OK with doing a. and b. The problem with c. is that making a cross platform script requires time but we could make it work for us at least. Note that this leaves open what 'mvn clean install' should do. Thoughts? Emmanuel
