Maven_gemify.rb can't find ruby-maven?

Hello all,

I’m not sure if this is actually a bug or my misunderstanding of the
feature. I’m trying to use the maven_gemify.rb code (“borrowing” some of
the in-process integration with Maven to do some cool stuff, actually :wink:
and I had thought that the code intended to automatically use the
ruby-maven gem if it was installed. However, I just get the “can not
find maven3 installation. install ruby-maven with…” error.

Looking at the code it looks like you still have to add the bin
directory of the ruby-maven gem to your PATH for it to be detected. Is
that intentional? If so I’m not sure why the code looks for the gem in
the first place since it also has a “mvn” binary and works perfectly
well as a regular Maven installation.

If nothing else the error message is deceptive since just installing the
gem won’t resolve the issue by itself.

Cheers,
Robin

hi,

the next incarnation of maven_gemify.rb is
https://github.com/mkristian/jbundler - not exactly a replacement . .
.

but anyways jbundler uses the jars from ruby-maven to do ts stuff and
does not fall back on a maven install since the internal jars supplied
by maven3.0.x are not all binary compatible to each other.

maybe jbundler is a better starting point for you !?

Interesting, although not as useful for my case as I’m trying to
leverage the code in maven_gemify.rb that launches Maven in-proc, rather
than shelling out. Thanks for the tip though!

OK - one more trial :slight_smile:

maybe ruby-maven gem is helpful ?

require ‘ruby-maven’
rmvn = Maven::RubyMaven.new
rmvn.exec_in(’/my-project’, ‘install’)

this works both with jruby as well MRI. MRI launches ‘java’ and jruby
it will launch it directly inside the same JVM (in the similar manner
as maven_gemify)

after writing the last email I realized that I did things were not as
I remembered them to be and altogether the gem was not useful for
others. so I straighten things a bit and also made sure when running
on jruby maven will execute on the same JVM. overall the code is
cleaner and more straightforward then what I did in maven_gemify.rb.

you also need before executing maven.

mvn.options[’-f’] = ‘pom.xml’

a flaw in the API :frowning:
