OFBiz uses BuilbBot as its Continuous Integration (CI) tool. There are other CI tools used at the ASF. There is also a file in Git for project paths. You can't clone, but you can make PRs inside it AIUI, via the github UI, just make a new branch and PR it. More information about creating a new branch below.
Here is the OFBiz BuildBot script (ofbiz.py). If you are interested on modifying it, please understand its content and read the BuildBot documentation. Note that the Infra team is always there to help you. If you modify ofbiz.py be sure to be subscribed to private@infra.apache.org before. It's where the syntax checker can help you in case of issues. I think that not everybody can be subscribed, at least ASF members, and maybe more, better check with Infra team when needed.
BuildBot uses schedulers and builders. Schedulers decide which builders to trigger on Git commits.
You can see the OFBiz builders and their states in the common Buildbot builders view (look for “ofb” or just scroll down).
The ofbizTrunkFramework builder is triggered on commits in the trunk framework branch. Then only the framework integration tests are run. This also triggers the ofbizTrunkFrameworkPlugins if the build succeed. Then the whole integration tests are run. To check that a commit in the framework puts no regressions in plugins and especially because the dependencies of ofbiz-framework without ofbiz-plugins is different from the dependencies of ofbiz-framework + ofbiz-plugins (plugins components are Gradle sub-projects). So testing needs to happen in both scenarios because you might face library version bugs.
Of course a commit into the trunk plugins also triggers the ofbizTrunkFrameworkPlugins.
The same apply to the current stable version (eg ofbizBranch18Framework and ofbizBranch18FrameworkPlugins) and next releases branches, they follows the same structure than the trunk.
In an OFBiz builder page you can see an history of the builds up to 100. You can see more by using the settings page. You may want to explore more to get acquainted with the tool...
There is also the RAT builder. It checks the licenses in OFBiz. You can find the trunk results here. There are also RAT builders for the next and stable release branches.
Here are the trunk test results. The framework results contain only the framework integration tests while the plugins results contain all the test for framework and plugins. You can find the same for the next and stable release branches.
When you create a new branch you need to let know BuildBot about it. This because BuildBot uses Git hooks to triggers builds on commits. The file to change is here. You can't clone, but you can make PRs via the github UI, just make a new branch and PR it.
Sometimes (rarely) you can get transient tests errors in BuildBot. This mean tests don‘t all pass in BuildBot, though they pass in your local instance. In such case, it’s most certainly an issue with servers. Those are hard workers and make errors from time to time, which shows that not only human make errors.
Before doing anything it's best to check which BuildBot step is impacted, and if it exists have a look at the logfile (stdio)
Some other errors may happen, like
In such case you can trigger a build from IRC to see if the problem resolves by itself. This is currently no longer working, see https://issues.apache.org/jira/browse/INFRA-22297. So you need to make a small non functional reversible change, pushing it and later reverting it.
Most of the time tests and issues are resolved this way. If it does not then the best is to ask Infra help, either on Infra Slack channel or by creating an Infra Jira issue.
When something like that happens, I get to IRC (I use https://web.libera.chat/, of course you can pick your own). There using a recognisable username (I use jleroux) I get to the #ofbiz channel. I use ofbiz-bot to make a request in the chat line at bottom to restart a build.
A request is of the form
force build ofbizTrunkFramework
you can put the text you want to appear in builder, after this expression, something like
forces manual build after weird error
So the whole request is of the form
force build ofbizTrunkFramework forces manual build after weird error
Note that with our last config (see INFRA-15394) the plugins builders are dependent and automatically launched by the framework builders but only on commits. So if you use an IRC command like force build ofbizTrunkFramework only this builder will be launched not the dependent ofbizTrunkFrameworkPlugins. We can't call a scheduler from IRC. It needs a Git commit.
Though today (2021-12-31) this seems to not happen anymore, one case which comes back from time to time is a conflit on port 8080 due to the automatic startup of tomcat. It's due to security patches being applied on one of 3 the servers BuildBot uses for OFBiz, hence the random aspect. In such case we need to ask infra to manually disable Tomcat on this server. This happened 4th times already, last case was INFRA-15829 where things are best explained.
