Subject [jelly] enhanced new tag, and maven repo update needed (was cvs commit: jakarta-commons-sandbox/jelly/...)
Date Thu, 28 Nov 2002 00:36:26 GMT
This commit extends the core:new tag slightly to add support for invoking
constructors that take arguments (see the commit msg and test cases for
details).  This functionality depends upon the new ConstructorUtils class
added to commons-beanutils earlier this week (this appears in the 27 Nov
nightly at least, maybe a bit sooner).  I guess this means the
beanutils-SNAPSHOT.jar in the maven repository at ibiblio needs to be
updated.

I know I've seen this answered before, but how do I go about getting that
snapshot jar updated?  A message to maven-user?  Do I need to subscribe to
that list to have it go through?  Is there a way we could get maven to
pull JARs out of the gump output or project-specific nightlies?

If you need it working in the meantime, I simply changed the beanutils
<version> tag to an arbitrary value and manually added the nightly build
of beanutils to my local repository.  There may be a cleaner way, but that
works at least.

Also, on an unrelated note, I notice that the
org.apache.commons.jelly.ant.TestJelly suite is failing (12 tests, 4
errors), at least for me.

  Log:
  * allow <new> to invoke constructors with arguments, as specified by <arg> tags
  * allow <new> and <useBean> as <arg>s, in addition to basic <arg>
  * extract BaseJellyTest and BaseClassLoaderTag classes
  * add tests for <new> and <arg>
  * NB: this makes jelly depend upon "nightly" versions of commons-beanutils dated 2002-11-27 or later, the maven repository needs to be updated to support this (about to send a note to commons-dev regarding that)
