Hello Naresh

I had the same problem with slightly different Liferay 6.2 versions:
<liferay.version>6.2.10.15</liferay.version>
<liferay.maven.plugin.version>6.2.10.13</liferay.maven.plugin.version>
and Java 8.

After some searching and reading it seemed to me that somehow the liferay-maven-plugin does some "magic" to enable Ruby/SASS processing during the build-css goal.
Some Ruby gems seem to be extracted to the local temp folder and made available under: ${java.io.tmpdir}/liferay/ruby/gems/, with "java.io.tmpdir" being the system's temp folder.
Source: https://web.liferay.com/de/web/kzhang/blog/-/blogs/resolve-the-sass-syntaxerror-invalid-css-error-in-liferay-6-1

What I did just for tests: remove that temp folder ("rm -rf /tmp/liferay/ruby/gems/" in my case) and watch what happens.

And here's what happened:

• suddenly the build succeeded
• nothing new got extracted or copied to the tmp/liferay/ruby folder, contrary to the description under the link above. But maybe the depicted workaround was abandoned in the time since April 2013.

I guess/hope that after three months you already found a solution for yourself.
But maybe this is at least helpful for others.

Regards,
Alex
