Jenkins parameters from property file based on global env vars

Question

Context:

input parameters to jenkins job are defined in a property file. property file location changes based on environment in which jenkins is running

ex: for dev environment path be like /app/dev/some/nested/path/propertyfile

for prod environment path be like /app/prod/some/nested/path/propertyfile

presently using extended choice parameter plugin to read property file. this works well if path to property file is absolute.

Problem:

is there a way to include global env variable in property file path? can it be done using active-choices plugin?

Answer 1

using active-choices plugin

def choices=[]
textFile= new File("/app/${Gloabl_Var}/some/nested/path/propertyfile")
textFile.eachLine{ line ->
if(line.startsWith('<Property-Key-Name>')) {
 line.split('=')[1].split(',').each {
choices.add(it)
}}}
return choices

using extended choice parameter plugin

can't use property file directly, will need to use groovy script

import hudson.slaves.EnvironmentVariablesNodeProperty
import jenkins.model.Jenkins
def global_env_var=Jenkins.get().globalNodeProperties.get(EnvironmentVariablesNodeProperty.class).envVars['<Global_Var>']
def props = new Properties()
def stream = new FileInputStream("/app/${global_env_var}/some/nested/path/propertyfile")
try {
props.load(stream)
} finally {
stream.close()
}
return props.getProperty('<Property-Key-Name>').split(',')
