Fix JENKINS-13119

I added the ability to evaluate a Groovy script in 'Prepare environment for the build' section

For example, you can have the following script:
if (CASE==null){
return null;
}

def stringValue="StRinG";

if ("upper".equals(CASE))

if ("lower".equals(CASE)){
def map = [COMPUTE_VAR: stringValue.toLowerCase()]
return map
}

This script injects the environment COMPUTE_VAR in the following job steps.
As you can see, this variable is computed according the CASE variable value.
This variable comes from a parameter value (given by the user).

The only restrictions are:

• The script has to be in Groovy (close to Jenkins core, written in Java/Groovy)
• The script has to return a Map Java object (all the map elements will exported as environment variables).

Please upgrade to EnvInject 1.38.
Let me know if it suits you.

Thank You so much Greg for your quick response, with a plugin update!!!

I installed EnvInject 1.38, added similar groovy script to my job and tried to build it. I got the below error.

[EnvInject] - Preparing an environment for the build.
[EnvInject] - [ERROR] - SEVERE ERROR occurs: com/sun/xml/internal/ws/server/UnsupportedMediaException

I think I have to add required jar to class path of JBOSS AS 7 I am using for jenkins, which I do not know how to. I am trying to find out how to do that. Could you please let me know how to do that, if you already know about it?

I will provide an update once I am able to successfully use the updated plugin to set environment variables based on user input.

Thank You once again for your effort.

Maybe a JBOSS issue with Groovy.
Do you have the ability to test on another servlet container such as Tomcat?

I am able to to put the required jar file in the lib folder of jenkins.war and I am able to use ENVInject successfully.

Right now I am trying to test Evaluated Groovy script. Tried the below and got and error

[EnvInject] - Evaluation the following Groovy script content:
if (MODULE_NAME==null)

if ("ACCT".equals(MODULE_NAME))

if ("FPD".equals(MODULE_NAME))

[EnvInject] - [ERROR] - SEVERE ERROR occurs: startup failed:
Script1.groovy: 3: expecting '}', found 'return' @ line 3, column 70.
p = ["MODULE_HOME": "SSP-AM"] return map
^

1 error

Greg,
I am able to successfully run the groovy script that serves my purpose. I really appreciate your help and time. You are very responsive and quick

Below is the log. MODULE_NAME is provided by user when performing build.

[EnvInject] - Evaluation the following Groovy script content:
if(MODULE_NAME.equals('ACCT'))
{
def map = ["MODULE_HOME": "SSP-AM"]

return map;
}

if(MODULE_NAME.equals('FPD'))
{
def map = ["MODULE_HOME": "SSP-FPD"]

return map;
}

Building in workspace /usr/J2EE/JENKINS/jobs/TEST_GROOVY/workspace

+ echo MODULE_NAME:FPD
MODULE_NAME:FPD
+ echo MODULE_HOME:SSP-FPD
MODULE_HOME:SSP-FPD
Finished: SUCCESS

Try to use return line

Copy paste the following script, it should work

if (MODULE_NAME==null)

if ("ACCT".equals(MODULE_NAME)){
def map = [MODULE_HOME: "SSP-AM"]
return map
}

if ("FPD".equals(MODULE_NAME)){
def map = [MODULE_HOME: "SSP-FPD"]
return map
}

Wiki removes return line.
Otherwise, add a semicolon, for example:

if (MODULE_NAME==null)

if ("ACCT".equals(MODULE_NAME))

if ("FPD".equals(MODULE_NAME))

I have this groovy script:

if (BUILD_TYPE.equals('Trunk')) {
def map = [SVN_REPO_PATH: "trunk/ConfigManagement"]; return map;
}
if (BUILD_TYPE.equals('Branches')) {
def map = [SVN_REPO_PATH: "branches/${SVN_BRANCH}"]; return map;
}
if (BUILD_TYPE.equals('Tags')) {
def map = [SVN_REPO_PATH: "branches/${SVN_TAG}"]; return map;
}

Where BUILD_TYPE is a CHOICE type user parameter which has Trunk, Branches, Tags in the drop down.

The build keeps failing with,

[EnvInject] - [ERROR] - SEVERE ERROR occurs: No such property: BUILD_TYPE for class: Script1
Finished: FAILURE

Please Help

Additional Info: SVN_BRANCH and SVN_TAG are other user input parameters.

I suggest you should replacing the condition BUILD_TYPE.equals('Trunk') by "Trunk".equals(BUILD_TYPE).
Inverting the conditions avoids a NullPointerException.
Could apply this principle to all conditions and let me know?

Gregory, First let me just thank you for such a prompt response. Honestly speaking I am not a big fan of open source mainly because of support. But my view is already changing.

Having said that, I did what you request me and the issue persists. complete details follow:

Started by user Anup Singh
[EnvInject] - Loading node environment variables.
[EnvInject] - Preparing an environment for the build.
[EnvInject] - Keeping Jenkins system variables.

}
if ("Tags".equals(BUILD_TYPE)) {
def map = [SVN_REPO_PATH: "branches/${SVN_TAG}"]; return map
}

[EnvInject] - [ERROR] - SEVERE ERROR occurs: No such property: BUILD_TYPE for class: Script1

Problem solved...got rid of curly braces around SVN_BRANCH and SVN_TAG. However its weird that I still has to use the $ sign in front of it but I have to use BUILD_TYPE without the preceding $.

if ("Trunk".equals(BUILD_TYPE)) {
def map = [SVN_REPO_PATH: "trunk/ConfigManagement"]; return map
}
if ("Branches".equals(BUILD_TYPE)) {
def map = [SVN_REPO_PATH: "branches/$SVN_BRANCH"]; return map
}
if ("Tags".equals(BUILD_TYPE)) {
def map = [SVN_REPO_PATH: "tags/$SVN_TAG"]; return map
}

Can somebody help me out...

I am using :
def matcher = manager.getLogMatcher("ServerName=(.*)")
if(matcher != null) {
servername = matcher.group(1)
manager.addShortText("$servername")
def map = ["Sony": "hello"]
return map
}

And the console output is:
C:\Users+++++++++\.jenkins\jobs\servernamepoc\workspace>powershell d:\scripts\servername.ps1
ServerName=hahaha

C:\Users++++++++\.jenkins\jobs\servernamepoc\workspace>exit 0
[EnvInject] - Injecting environment variables from a build step.
Finished: SUCCESS

However on checking the respective job's environment variables - it doesn't shows up...

Any help is appreciated.
