Jenkins Bitbucket PR构建错误而没有清除工作空间

Question

我有一个像这样的詹金斯人

job('jenkinsjob') {
    description('')
    logRotator(7, -1, 7, -1)
    parameters {
        stringParam('PULL_REQUEST_ID','','Pull request ID (populated by Bitbucket Webhook)')
        stringParam('PULL_REQUEST_URL','','Pull request URL (populated by Bitbucket Webhook)')
        stringParam('PULL_REQUEST_TITLE','(no title)','Pull request title (populated by Bitbucket Webhook)')
    }
    authorization {
        ...
    }
    label('java')
    wrappers {
        timeout {
            elastic(300, 3, 30)
        }
        preScmSteps {
            steps {
                systemGroovyCommand('''def url = build.buildVariableResolver.resolve(\'PULL_REQUEST_URL\')
def id = build.buildVariableResolver.resolve(\'PULL_REQUEST_ID\')
def title = build.buildVariableResolver.resolve(\'PULL_REQUEST_TITLE\')
build.description = "PR #${id}: <a href=\'${url}\'>${title}</a>"''')
            }
            failOnError(true)
        }
    }
    scm {
        git {
            remote {
                name('origin')
                url('ssh://git@git.mycom.com/team/project.git')
            }
            branches('origin/pr/master', '*/release/**', '*/bugfix/**')
            extensions {
                // wipeOutWorkspace() // ***** comment out to speed out build. ******/
                localBranch('$GIT_BRANCH')
                mergeOptions {
                    remote('origin')
                    branch('master')
                    strategy('default')
                    fastForwardMode(FastForwardMergeMode.FF)
                }
            }
        }
    }
    triggers {
        ...
    }
    steps {
        shell('''
npm install
        ''')
      ...
    }
    publishers {
      ...
    }
}

当我使用wipeOutWorkspace时，一切正常。问题是npm安装需要很长时间，因为它是一个干净的工作区。

在注释掉wipeOutWorkspace之后，构建因以下错误而失败：

有没有一种方法可以进行快速的公关构建而无需每次都清除工作空间？
