Reproduction steps:
(1) Change Manage Jenkins settings to allow Jenkins to have 4 executors.
(2) Add following file to depot as '//depot/myLibrary/src/org/foo/lib.groovy'
package org.foo;def dispEnv () { echo "All Environment Variables" if (isUnix()) { sh 'env' } else { bat 'set' } }def testFunc () { echo "HELLO FROM testFunc version 3." dispEnv() }return this;
(3) Create a Modern SCM library:
(4) Create a job that uses the library and allows concurrent builds.
@Library('my-shared-library') import org.foo.lib.* pipeline { agent any stages { stage("Repro") { steps { script { def z = new org.foo.lib() z.testFunc() sh('sleep 20') } } } } }
(5) Run build 4 times.
(6) Look at 'workspace' directory on build machine to see that @libs for the job now contains 4 text files and 4 folders.
(7) Wait till all jobs complete.
(8) Run build 4 times immediately.
(9) Look at 'workspace' directory on build machine to see that @libs for the job now contains 8 text files and 8 folders.
