I'm using the Groovy Grails Tool Suite to practice Groovy. I want to run a Groovy Shell, but when I create a new shell and try to run it, I get this error:
Could not find $jarName on the class path. Please add it manually
What does this mean, and how do I resolve this?
I believe this is happening because JLine can't be found on your classpath. I submitted a PR to make the error message in this case actually useful.
I had a similar problem with this exact same message, but the reason was that I was attempting to run the script without specifying which script to run. Ensure you have the script open in the editing window and trying running it again - that got rid of the message for me.

I'm trying out NetBeans for editing Groovy code. (I'm new to Groovy, and it's been a long time since I did any Java development).
At some point I installed the Groovy plugin via the "plugins" tool. But it does not have the green checkmark under "active", and choosing the Groovy plugin does not make the Activate/Deactivate/Uninstall buttons available. Oh well...
So let's create a project...
Choose "new project". I'm choosing "Java with Maven" just because it's the first one.
Hit "Finish"...and voila, I have a project.
Let's create a file...
Right click the project package in the left pane, choose "new"
Choose "Groovy Script" for a type, hit "finish"
Hey, I have a very simple script. Looks like it should say "Hello chris!" when done.
Hit the "play" button on the toolbar....things appear in the output window.
But wait a minute...the output is "Hello World!", and it should be "Hello chris!" It looks like "HelloWorld" is coming out of "Mavenproject1.java".
How can I (or can I) just run my script from within NetBeans?
UPDATE: per #andrewJames suggestion, I tried working that tutorial. (It looks like the tutorial may be a bit out of date.)
I created a "Java Ant" project, as that was the only one that offered me the option of not creating a "Main Class File".
I created the Java form, and the Groovy class, as directed.
When I run the project, I get an error message saying "Error running forked groovyc".
I get that same error whether I'm running on a machine with a groovyc executable or not, so I suspect that there's something about the configuration that I need to change in order to point to the groovyc executable.
Probably something to do with the build.xml file...but I can't seem to figure out how to edit that to change the search path for the groovyc step.
I had the same problem that NB doesn't run a Groovy script out of the IDE like Eclipse does. I logged an issue and spent more than a year on the netbeans-dev mailing list advocating for it. Often replied to with "we'll be happy to review your pull request" type of stuff. Eventually, when I rage quit the mailing list with a scathing message, Geertjan replied to the issue with a solution.
So, in short, use the old plugin to create a Groovy project and change line 26 in groovy-build.xml to
<groovyc srcdir="#{srcdir}" sourcepath="#{sourcepath}" destdir="#{destdir}" encoding="${source.encoding}" excludes="#{excludes}" includeAntRuntime="true" fork="false">
You can then run your script with Shift+F6.
The project needs the Groovy jars added. It works for me on NB 11, 12 & 13 with Groovy 2.x and Java 8, 11 & 14 so far. I haven't tried it with Groovy 3.x as the groovy-all.jar is deprecated so you'll have to maven or manually manage the Groovy jars.
Also, I collaborated a bit with someone on a new plugin. It works as is but new development has stalled.
I have certain errors which I set in my code, which should add corresponding error messages to the email content of the final build email.
I was thinking of printing something such as ("EMAIL CONTENT ERROR: _______") to the console, reading through it (in a pre-send groovy script?), and adding corresponding error messages for each error found.
I was thinking of using a pre-send groovy script, setting the mimeMessage object(was reading jenkins email-ext documentation). Would this be viable?
Also, I have never used groovy before, so pointers to how to approach this would be extremely helpful(or a link to where i can find an implementation of something with a similar idea of reading console). Any advice would be greatly appreciated. Thanks in advance!
Can you check attaching "Build Log" This would highlight all the process of build process.
This is a very similar concept to the question here. The technique there was to use the log parser plugin to scan the console output for you, and then use groovy to add all the errors into an email.
This is generally a pretty good idea because it also means that you can view the same set of highlighted errors from jenkins itself, rather than just the email.
There are a couple of ways this is different from your setup, the main points are:
Yes, write errors directly to the console in a known format
Set the log parser up with regular expressions that find your error format
Instead of a pre-send script, in this case you would use a groovy template for your email generation
The template reads the error list from the console parser and adds them to your email. Each one is a link that links back to the jenkins console output.
I really like being able to run Groovy scripts in Hudson (or Jenkins, but I use Hudson).
For example, see my question In Groovy, how do I get the list of parameter names for a given job? Hudson parameter names question][1]
The thing is, now I'd like use these Groovy scripts like a keyboard macro or utility. I want to be visiting one of my jobs, hit the special keystroke, and voila, the Groovy script is run. I leave it as an exercise for myself to pick up parameters from environment of current job.
Does anybody out there do this sort of thing, and if so, what strategy has been useful. So far, all I know how to do is bring up the script console, pasted in my code, edit the variable containing the name of the Hudson job, and hit "run". Kinda klunky. Suggestions appreciated.
You can use jenkins Remote access method to do this. The Jenkins wiki describes how to use Remote access:
User can execute groovy scripts remotely sending post request to
/script/ url or /scriptText/ to have response returned without the
html wrapping.
$ curl -d "script=<your_script_here>" http://jenkins/script
$ # or
$ curl -d "script=<your_script_here>" http://jenkins/scriptText
Also, Jenkins CLI offers the possibility to execute groovy
scripts remotely using groovy command or execute groovy interactivelly
via groovysh.
I have a question very similar to this: Reading file from Workspace in Jenkins with Groovy script
However I need to read the file from a System Groovy script so the solution of using Text-finder or the Groovy PostBuild plugin will not work.
How can I get the workspace path from a system groovy script? I have tried the following:
System.getenv('WORKSPACE')
System.getProperty("WORKSPACE")
build.buildVariableResolver.resolve("WORKSPACE")
Thanks!
If you have a file called "a.txt" in your workspace, along with a script called "sysgvy.groovy" that you want to execute as a system groovy script. Suppose your "sysgvy.groovy" script needs to read the file "a.txt".
The issue of this topic is that if your script read "a.txt" directly without providing any path, "sysgvy.groovy" executes and will throw an error saying cannot find "a.txt".
I have tested and found that the following method works good.
def build = Thread.currentThread().executable
Then use
build.workspace.toString()+"\\a.txt"
as the full location string to replace "a.txt".
It's also important to run on the Jenkins master machine by placing "a.txt" and "sysgvy.groovy" onto Jenkins master machine's workspace. Executing on slave machine does not work.
Try it, the file should be found and get read in the script without any problem.
If there is problem with variable Thread, it is just that some modules need to be imported. So add these lines to the start of code:
import jenkins.*
import jenkins.model.*
import hudson.*
import hudson.model.*
Each build has a workspace, so you need to find the desired project first. (The terms "job" and "project" are used rather interchangeable in Jenkins - also in the API.)
After that, you can either cross your fingers and just call getWorkspace(), which is deprecated (see JavaDoc for details).
Or you can find a specific build (e.g. the last), which can give you the workspace used for that specific build via the getWorkspace() method as it is defined in the AbstractBuild class.
Example code:
Jenkins.instance.getJob('<job-name>').lastBuild.workspace;
Just use
build.workspace
The "build" variable is available keyword in System Groovy Script.
I am new to FSL, using version 4.1.8. I am trying to run a script that reads and generates *.nii files, which format is normally supported by FSL. I am calling an FSL function, probtrackx from within Matlab. However, I get the following error message seemingly unable to generate or recognize *.nii files:
** ERROR (nifti_image_read): failed to find header file for '~/Documents/fMRI_data/../DTI/fsl_dti/masks/target_mask_001'
** ERROR: nifti_image_open(~/Documents/fMRI_data/../DTI/fsl_dti/masks/target_mask_001): bad header info
ERROR: failed to open file ~/Documents/fMRI_data/../DTI/fsl_dti/masks/target_mask_001
ERROR: Could not open image ~/Documents/fMRI_data/../DTI/fsl_dti/masks/target_mask_001
The files do exist but FSL fails to recognize them. Any help as to how to correct the issue and get FSL to work properly would be most appreciated. I suspect it's a Linux settings issue, just not sure how to fix it. A solution to a related problem in a previous posting suggested adding ls='ls --color=auto'. I've tried it to on avail.
Some FSL tools assume that the $FSLDIR unix unvironment variable is set, which might not be the case in your MATLAB environment. You can fix that with something like setenv('FSLDIR', '/usr/local/fsl') (modified of course if your FSL installation is in a different place). Some also need the regular FSL setup script to be executed as well: system('. ${FSLDIR}/etc/fslconf/fsl.sh'). See also: http://www.fmrib.ox.ac.uk/fsl/fsl/downloading.html.
Instead of the more complicated probtrackx script, another thing to try first is simply:
system('fslhd ~/Documents/fMRI_data/../DTI/fsl_dti/masks/target_mask_001')
If this fails with the same error, then you know that you entered the path to the data incorrectly. For example, do you mean to have the .. in there?
Also, in the future, the best place to get FSL support is on their mailing list at: https://www.jiscmail.ac.uk/cgi-bin/webadmin?A0=fsl
Does MATLAB have access to run other fsl commands? If you are able to run a command from the command line but not through MATLAB, the MATLAB user may not have access to run fsl or may be looking for some FSL variables.
You might have to do the equivalent of this for a linux system
