"Couldn't compile the CSS from LESS sources" if plugin is located on network folder #183

ghost · 2015-11-09T09:56:46Z

When installing the build monitor plugin on my Jenkins system I receive the following error in the log:

The Jenkins working directory including the plugins is located on a network share, which is accessed by UNC path:

The path is displayed in the error message with only one leading backslash, instead of two.

If you need more details, please let me know.
Would be great if you could fix that.

Hey @adaubner and thanks for reporting this. What version of java are you running your Jenkins on? And what version of Jenkins do you have?
I'm wondering if the issue you're seeing could be related to a Jenkins bug JENKINS-26203 fixed in Jenkins 1.598.

ghost · 2015-11-17T07:10:11Z

Hi Jan.

Since yesterday we are running on Java 8u65.
Before that it was 7u79.

@adaubner - would you like to check if the latest version - 1.6+build.168 - resolved the issue for you?

Two things worth noting:

the fix requires Build Monitor to run on Jenkins 1.598 or later (due to a bug in Jenkins)
and Jenkins to run on Java 7 u60 or later (due to a bug in Java)

Please note: The version of Build Monitor mentioned in this ticket is not yet available on Jenkins Update Centre as it's a "beta" released to gather early feedback (changelog).
To install the plugin from a .hpi file go to Manage Jenkins > Manage Plugins > Advanced > Upload

Looking forward to hearing from you!

After a short look at google, this has to do with the UNC path. ☹

… the one applied in SBT: sbt/sbt#564) Build Monitor should load its LESS CSS assets correctly from a mapped network folder defined as a UNC path on Windows as long as: - Build Monitor runs on Jenkins 1.598 or later (due to a bug in Jenkins prior to that version: http://jenkins-ci.org/changelog#v1.598) - Jenkins runs on Java 7 u60 or later (due to a bug in Java prior to that version: http://bugs.java.com/view_bug.do?bug_id=8014394) Fixes #183

jan-molak · 2015-11-18T22:24:58Z

Hey Andreas,

Yes, you're correct. The problem is caused by the Java File class not handling the Windows UNC paths correctly. As mentioned in my previous post, Java 7 update 60 fixed this problem, and if you're using Jenkins >= 1.598 it can use that fix.

Many thanks for reporting the second problem, the one with the authority. This seems to be caused by a different issue with the File class, and the way it's interacting with the URI class... Oh joy ;-)

The latest build (1.6+build.169, available here) should work around that problem. Please give it a try and let me know your thoughts!

Looking forward to hearing from you,
Jan
