Subject RE: Please run with assert on when you're developing...
Date Wed, 12 Jun 2013 20:30:41 GMT
Some (ok one) have asked me what is MAVEN_DEBUG_OPTS.  That's my bad for not being clear.

Adding "-ea" to MAVEN_OPTS will cause assert to be on for maven and maven's plugins as well.
 That means during clean, install stages, you might hit some weird asserts (according to others
experience on the web).

So what I did is added it to the script mvnDebug which utilizes MAVEN_DEBUG_OPTS.  When I
run jetty:run, I always use mvnDebug which sets up the debug port for the jvm and with this
change also run in assert mode.  You always want to use mvnDebug for your own testing of the
server anyways because you can easily attach for debugging purposes.

The drawback to doing it this way is that the unit tests that are ran during the install stage
do not hit asserts.  (I think but haven't confirmed yet.)
