我创建了作业管道，然后尝试获取与Regexp匹配的所有作业，并在并行启动之后。我有例外：Jenkins v 2.5
node {
stage('deploy') {
def branches = [:]
def theJobs = Jenkins.instance.getAllItems(Job);
for(int i = 0; i < theJobs.size; i++)
{
def jobName= theJobs[i].getName();
if( jobName =~ /server-[0-9][0-9]..*/)
{
branches[i] = {
build job : "${jobName}", parameters: [[$class: 'StringParameterValue', name: 'BRANCH', value: "${BRANCH}"] ]
}
}
jobName = null
}
parallel branches
}
}

完成：失败
詹金斯管道已经变得如此强大，以至于可以在各种故障场景中恢复，例如主人或代理人下降。为了能够做到这一点，将存储管道的每个中间步骤，因此管道知道在发生故障时恢复的位置。
要存储管道步骤，它们必须为Serializable。在您的情况下， def theJobs = Jenkins.instance.getAllItems(Job);不可序列化，因为列表中的条目是 FreeStyleProject，而不是 implements Serializable。
解决方法的一种方法是将使用不可隔离步骤的所有代码移动到方法中，并用@NonCPS注释该方法。这会向管道发出信号，以免尝试存储此方法的结果，因此它不需要序列化。如果发生故障并需要在尚未执行步骤中的结果，则该方法将再次执行。
在您的示例中：
node {
stage('deploy') {
parallel getBranches()
}
}
@NonCPS
def getBranches() {
def branches = [:]
def theJobs = Jenkins.instance.getAllItems(Job);
for(int i = 0; i < theJobs.size; i++)
{
def jobName= theJobs[i].getName();
if( jobName =~ /server-[0-9][0-9]..*/)
{
branches[i] = {
build job : "${jobName}", parameters: [[$class: 'StringParameterValue', name: 'BRANCH', value: "${BRANCH}"] ]
}
}
jobName = null
}
return branches
}
