WTP Build Process and Procedures
This page is to collect general information and references about the WTP build process and procedures. The idea is that any WTP committer can update it, pretty much "on the fly" or "as you go", or "as needed", so that there will often be a bit of a disorganized, stream of consciousness flavor to it. Hopefully, occasionally, some kind-hearted committer will stop and organize all the miscellaneous notes and tips and references that are provided, into fun-to-read treasure that you just can't put down.
Note: since only committers can edit these pages, if anyone from the community has contributions or suggestions for additions, please open a [feature request] on our releng component.

As of February 1, 2006
Our WTP 1.0.1 contributions are due by EOD on Monday's, we smoke test that build on Tuesday's, and plan to declare it by Wednesday's at noon (eastern time).
Our WTP 1.5 contributions are due by EOD Wednesday's, we smoke test that build on Thursday's, and plan to declare it by Friday's at noon (eastern time).
The platform's releng tool should be used to "release" projects to the map files. Be sure to have the appropriate branch of releng project (which has the map files) loaded in your workspace. R1_0_maintenance for 1.0.x builds, and HEAD for 1.5 builds.
As projects are versioned, please use the "standard" format, in UTC time, following vYYYYMMDDHHMM. This is important as these cvs tags become the qualifier field of the plugin's version.
Note: do NOT use underscores in the CVS version, as there are some issues with Eclispe tooling when it finds an underscore in a plugin or version qualifier, see .
How to watch the builds
Do you enjoy watching screens of console logs fly by as much as I? Waiting for that joyous final result? Well you can do that with the following information.
We are currently doing our builds on build.eclipse.org. Any committer can logon to that surver using their committer ID and password. I use something like
Once there the main work we do is in /shared/webtools/. If you want to "watch" the console log while the compiiler and ant files are running, you can use
tail -f /shared/webtools/build-node/builder/cruise/cruise.out -n200
to watch the last part of the main log (during compile, etc.). This is the fastest way to find out if the build failed. Once it does fail, there's some diagnostic messages that might be informative in the last 20 or 50 lines. (Do be careful, though, the build always says "Build Successful" as its very very last message, and that message just means all the ant scripts were any to completely execute (not that they did so successfully).
During tests, you can watch test results console at,
tail -f /shared/webtools/test-wtp-S/results/consolelogs/wtptestlog.txt -n200
In fact, I do this so much, I define these aliases in my .bash_proflie
alias tailout='tail -f /shared/webtools/build-node/builder/cruise/cruise.out -n200' alias tailtest-i='tail -f /shared/webtools/test-wtp-I/results/consolelogs/wtptestlog.txt -n200' alias tailtest-m='tail -f /shared/webtools/test-wtp-M/results/consolelogs/wtptestlog.txt -n200' alias tailtest-r='tail -f /shared/webtools/test-wtp-R/results/consolelogs/wtptestlog.txt -n200' alias tailtest-s='tail -f /shared/webtools/test-wtp-S/results/consolelogs/wtptestlog.txt -n200'
Here the handy thing to watch for is if a test doesn't seem to make any progress at all, after 10-20 minutes. That's a sure sign of a hang. And, here's how to get some diagnotic information on Linux. First, "break out" of the tail program with ctrl-c. Then get a list of processes that are running by using
ps -ef | grep java
Usually, torwards the end, you'll see a task that mentions, in the long (wrapped) command line, a recognizable JUnit suite. For that process, looking toward the left of the long (wrapped) line, get its process ID ... usually 4 or 5 digits. Then (almost there!) type "kill -3 <process-id>". I forget exactly what the '-3' means to Unix, but to Java, it means to take a dump of current data and thread states, You'll see a few messages to the console that a java dump wsa greated. That's the file that's handy to attach to a bugzills. (use sftp copy, if you do not have handier tools). That file is usually located in the /eclipse directory in use during the test.
Feel free to edit this document with further tips (or, improve the directions above is I left out some steps, or, you've noticed things are slightly different than written here.
This section is just to make quick notes about changes to our build files/scripts that others might find intersting.
- Update prereqs to include official Eclipse M5.
/downloads/drops/S-3.2M5-200602171115/ eclipse-SDK-3.2M5-win32.zip eclipse-SDK-3.2M5-linux-gtk.tar.gz eclipse-SDK-3.2M5-linux-gtk-ppc.tar.gz eclipse-test-framework-3.2M5.zip
There was an "odd" note when I downloaded the PPC version ...
Eclipse fails to create a lock file with reason "No locks available." To launch eclipse you must disable file locking using the osgi.locking property. For example, you could launch eclipse as follows: "eclipse -vmargs -Dosgi.locking=none".
Thus, we *might* have to -Dosgi.locking=none on our PPC machine when we move to this M5 version of the base builder.
