Capture python script output from groovy

Camunda 7 Topics Discussion & Questions

Hi,

We are trying to run below groovy script from camunda but not able to capture the output of the python script.

my.groovy

def sout = new StringBuffer();
def serr = new StringBuffer();
def arg1 = "arg";
def sdir = new File("my/dir/path");
def task = "python get_text.py ${arg1}".execute(null, sdir);
// also tried     def task = "python ${sdir}/get_text.py ${arg1}".execute();
task.consumeProcessOutput(sout, serr);
task.waitForProcessOutput();
def actualOut= sout.toString();
if (actualOut.startsWith('Exception')) {
    // do something
}
else {
    println "${script_to_eval}";
}

get_text.py

# connect to gitlab and get content of a file in a particular repo
import gitlab
#perform operations
print(filecontent)

When i run the groovy script manually, i’m able to retrieve the output from python script and print the output to console, but when i try to run the same groovy script from camunda, it does not return anything, need some advice on how to proceed.

Note:
i have verified that the camunda is picking the correct python file by providing the complete path to the python script and also i have added python executable path to system env variables

Hi s55,

this sounds very compicated since Camunda already includes Jython as a scripting-language.

Also have you checked out this Thread. Take care with the Links to the documentation, some might link to an older Version of Camunda.

Best regards,
Clemens
