JUnit – the parameter list given by cobertura is too long
•
Java
I'm trying to generate code coverage reports using the cobertura plugin
I'm in POM This dependency exists in XML
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>cobertura-maven-plugin</artifactId>
<version>2.6</version>

<execution>

When I used this goal to build my project - U - B clean up and install cobertura: cobertura, I got the following error on my Jenkins CI
16:37:31 [ERROR] Failed to execute goal org.codehaus.mojo:cobertura-maven-plugin:2.6:instrument (default-cli) on project TestModule: Unable to execute Cobertura. Error while executing process.

The build succeeded on my windows machine, but failed on Jenkins When I downgraded the cobertura version to 2.5 1, but I got some parsing exceptions because cobertura for 2.5 1's parser and Java syntax are not up to date
Someone can help me make this applicable to 2.6 Cobertura version 0 and later
Solution
This borders on the relevant direction, but may help
This is caused by the limitation of Linux, where the size of the parameter cannot exceed 128KB. Please refer to the Linux kernel constant: max_ ARG_ STRLEN https://github.com/torvalds/linux/blob/master/include/uapi/linux/binfmts.h
In Jenkins, once you read / exceed a variable beyond this value, you will encounter this error In my example, I have a GitHub webhook that starts the Jenkins job and sets the payload parameter to a string > exceeding this limit Attempting to read this parameter raises this error
To solve this problem, I have a child job that uses rest API calls to read the parent value
You can fail the parent job, but you can start the child job in all cases Here is a slightly improved function I use to extract information (error checking and comments are removed for simplicity)
def get_parameter_value_from_parent():
host = 'https://[YOUR_COMPANY].ci.cloudbees.com'
this_build_url = os.environ.get('BUILD_URL')
request_auth = (JENKINS_USER,JENKINS_TOKEN)
url = '{0}/api/json'.format(this_build_url)
parameter_name = 'payload'
payload = ''
#
# Get the upstreamBuild number,and the upstreamUrl
# so we can put together a link to the upstream job
#
response = requests.get(url,auth=request_auth)
this_build = json.loads(response)
build_number = ''
short_url = ''
actions = this_build['actions']
for action in actions:
if action.get('causes'):
for cause in action.get('causes'):
build_number = cause['upstreamBuild']
short_url = cause['upstreamUrl']
parent_url = '{host}/{short_url}{build}/api/json'.format(host=host,short_url=short_url,build=build_number)
#
# Now get the payload from the parent job by making REST api call
#
response = requests.get(parent_url,auth=request_auth)
upstream_build = json.loads(response)
actions = upstream_build['actions']
for action in actions:
if action.get('parameters'):
for parameter in action.get('parameters'):
if parameter['name'] == parameter_name:
value = parameter['value']
payload = value
return payload
print 'Error: Unable to return payload from parent jenkins job: {0}'.format(parent_url)
sys.exit(1)
