Accessing file on slave node from email-ext script (groovy)

[Bryan Hunt]

New subscriber here...

I have searched through the archives looking for an answer but haven't yet been able to find a solution to my problem (even though it appears this question has been asked before)

I have specific build output that I need to load into my email-ext script (a specially formatted version string) so I have the following code in the start of my groovy script which works fine if everything is executed from the master but fails otherwise

<% def versionString = ""

fr = new FileReader(build.workspace.toString() + "\\Build\\version.txt")

if (fr != null) {

versionString = fr.readLine()

} %>

Produces the following error:

        Exception: javax.script.ScriptException: java.io.FileNotFoundException: c:\jenkins\workspace\project_name\Build\version.txt (No such file or directory)

So aside from the obvious need for a try/catch block does anyone have a recommendation for loading a file from a slave?

Regards,

Bryan H.

P.S. Is there a way to change the MimeMessage.subject from inside the groovy body script (or do I have to ask my administrator to kindly update the plugin to a version > 2.22)?

You probably want to look at the FilePath [1] documentation and use that in the script. As for modifying the subject, you will need to upgrade to >2.22 for that.

Thanks,

Bryan,

FYI ...  have you tried to achieve the same result using JELLY scripting?

Thanks that is exactly what I needed. I ended up using the following:

<% def versionString = ""

def channel = null

if (build.workspace.isRemote())

{

channel = build.workspace.channel

}

fp = new hudson.FilePath(channel, build.workspace.toString() + "\\Build\\version.txt")

if (fp != null) {

versionString = fp.readToString()

} %>

Which appears to work well. I'm sure there is a much cleaner way of doing it (so if you have suggestions by all means send me an email).

As far as working around the outdated mod problem of modifying the subject I ended up having my build script dump my email subject and using ${BUILD_LOG_REGEX, regex="my_subject_regex", linesBefore=0, linesAfter=0, maxMatches=1, showTruncatedLines=false} in the email-ext subject line to pick it up thus accomplishing the same thing I was doing with a pre-send script.

Yes... It just really couldn't get jelly script to work to my satisfaction. Probably if I had more experience and better tools loaded my opinion might change but "JellyException: Could not parse Jelly script : null" isn't a particularly enlightening error.

Your right ..  I had to play around with the different jelly tags for it to work in a jelly script:

 

The best solution that works for me in a jelly script:

 

<h:parse html="MY_FILE.txt" var="rep_content"/>
       <br/>

<TABLE>
<TR><TD><PRE>${rep_content.asXML()}</PRE></TD></TR>

</TABLE>

 

FYI... the use of the <util:file and <util:loadText tags did not work for me at all ... I just kep getting a null value.
