Maven and Turbine-2 -- Is it usable at all?
Hi,
after an unsuccessful try to compile Maven myself on Linux, I fetched
the version for download from the web pages. BTW:
http://jakarta.apache.org/turbine/maven/download.html: maven-install-b3.jar
http://jakarta.apache.org/turbine/maven/start/download.html: maven-install-1.0-b4.jar
(Great. Quick, what was this tool for? :-) )
As the main problem with the b3 seems to be that it is imcomplete, I
decided to go with b4. Setting it up went smooth.
Now I fetched the current Turbine snapshot (from nightly/2002-06-03).
According to the docs, running simply "ant" in the root directory
should build the jar.
% ant

Buildfile: build.xml
maven:jar:
update-pom-check:

toVersion -> 3

Hm. Aha. So It does not. Maybe the update can be performed. Let's try the suggestion:
--- cut ---
henning@forge 18:50 ~/jakarta-turbine-2 > ant maven:available-updates
Buildfile: build.xml
BUILD FAILED
Target `maven:available-updates' does not exist in this project.
Total time: 1 second

Seems to be "early advertising". :-)
According to the maven docs (and the update sub directory, it should
be possible to upgrade the POM from v1 to v2 and from v2 to v3. At
least the v1-v2 and v2-v3 subdirectories seem to suggest this.
According to the plugins/core/build.xml, this should be possible:
v1 to v2 -> ant -Dmaven.fromVersion=1 -Dmaven.toVersion=2 maven:update-descriptor
--- cut ---
% ant -Dmaven.fromVersion=1 -Dmaven.toVersion=2 maven:update-descriptor
Buildfile: build.xml
BUILD FAILED
Target `maven:update-descriptor' does not exist in this project.

Ok, at this point I give up. I'll rip out the maven stuff from my
personal turbine builds and go back to the legacy build system. What
use is the new, shiny maven if you can't use it with the _actual_
current code from jakarta. There are no alphas, no betas. Just
Snapshots and CVS. :-(
I'd be really happy to use maven myself; it really looks
promising. But instead of adding it to more and more projects, it
might be nice to get it to work with the current projects first. :-)
Regards
Henning
