I am using kubernetes plugin to build my ci environment on a kubernetes cluster. There is a pipeline block like below:

stage ('Compile client & go src') {
dir('./src/main/docker/go/src/portal') {
sh "pwd; \
cd /home/jenkins/workspace/portal_v3.0/src/main/docker/go/src/portal/; \
export GOPATH=${env.WORKSPACE}/src/main/docker/go; \
gvt restore || true"

}

}

but the sh block fails from time to time. In the console output there are even incomplete log like this:
[Pipeline] }
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (Compile client & go src)
[Pipeline] dir
Running in /home/jenkins/workspace/portal_v3.0/src/main/docker/go/src/portal

It the last line, the word "workspace" was truncated to "wo".

I tried 5 times. it fails 2 times and success 3 times.

I do not think it is a dupe of JENKINS-46545 because I have many time success
