Hi @ratnamGT,

As stated at the bottom of this readme, you no longer require the git-jenkins.sh wrapper scripts with the recent versions of the Jenkins Git Plugin.

Which release of the Git Client plugin are you using? See the full list here:
https://plugins.jenkins.io/git-client/releases/

I removed the file git-jenkins.sh from the tools but again same error

Depending on the version of git on z/OS Unix Services, you may need to change the 'file.encoding' to IS08859-1, as we have documented in the cookbook.

• What is your version of Git on USS?
• Can you share the startup log including the environment variables for the Jenkins node?

Please double check the environment variables :

export JAVA_HOME=/usr/lpp/java/J11.0_64/
export IBM_JAVA_ENABLE_ASCII_FILETAG=ON
export IBM_JAVA_OPTIONS=""
export GIT_SSL_NO_VERIFY=true
export _BPXK_AUTOCVT=ON

and btw - /usr/lpp should not be used as the build workspace. The file systems mounted under this directory, is typically read only. Please double check your Jenkins node configuration.

@dennis-behm I am using git plugin 4.14.3

[ratnamGT]

Hi @dennis-behm

git version on uss is -git version 2.26.2-87
I have not setup environment variable for jenkins node.
I have access on /usr/lpp so used this path as build workspace I have tried other path also as build workspace
below are the jenkins configuration and startup logs without git-jenkins.sh file. Please let me know if you require other information

[dennis-behm]

Hi @ratnamGT

I see -Dfile.encoding=UTF-8 . Can you please switch to -Dfile.encoding=ISO-8859-1?

Please also add an && env into the Prefix Start Agent Command. This will print all the messages to the log of the Jenkins node.

And just to confirm the ikannode is the zOS agent node?

[ratnamGT]

Hi @dennis-behm

Thanks your help. -Dfile.encoding=ISO-8859-1 worked . But another issue is z/OS agent is getting offline automatically however it showing 'connected successfully in the logs.Also I increased the disk space on z/OS but it is still showing the diskspace error. This issue is occurring in my Jenkins instance inside the VDI but not in another jenkins instance which ,i am using from different environment. Could you please help me on this?

[dennis-behm]

@ratnamGT - please see the Jenkins books about node monitoring and thresholds - https://www.jenkins.io/doc/book/managing/nodes/

The default threshold settings might be too high compared to the free space on the mounted disk of the node in USS.

Hi @dennis-behm Thanks for your help.
Issue is resolved
