[m2] build fails on compiler warning

Maven version: 2.0-beta-1-SNAPSHOT, and
Maven version: 2.0-alpha-3

Hi,

I'm attempting to compile a class that contains the now reserved word
'assert' as a identifier.

This compiles fine, with the requisite warnings, outside of m2.

Under m2, the compiler:compile goal produces the warnings and actually
compiles the class BUT the build fails [Listing 1].

I would expect the build to pass in this case.

Previously on this list I have seen it suggested that setting the source
compatibility to 1.4 may fix this. In my case, setting this [Listing 2]
results in no warning, no class file and a failed build [Listing 3].

Any suggestions on how I can get around this?

Even if I do away with the assert, will m2 fail the build on any
compiler warning?

Cheers,
...andrew

scm:update error

Posted by Mariano Stampella <ms...@gmail.com>.
Hi, I'm Mariano with the same old problem, I use the scm-plugin and when try
to use the update goal occurs this

[WARNING] Unknown status: '? '.
[WARNING] Unknown status: 'M '.

That's because when i execute the update goal really executed this:

cvs -f -q update -d

And the result is:

? .xdoclet
? bin
? example
? iaso.ear
? manga.jpg
? xdoclet-build.xml
? j2ee/jars/javax.servlet.jar
M .classpath
M maven.xml
M project.properties


For this reason the update process is truncated.

Somebody can a solution for that?

Thanks

Mariano

Re: [m2] build fails on compiler warning

Posted by Brett Porter <br...@gmail.com>.
This is a bug, that it cannot parse the warning as a warning. Please
file it and we'll get it fixed before the next release.

Thanks,
Brett
