我有以下几点Jenkinsfile:

#!groovy

def projectPath = "${projectPath}"
def specPath = "${specPath}"
int numberOfRetries = "${NUM_OF_RETRIES}".toInteger()

def failure = true
def retryAmount = 0
def start = System.currentTimeMillis()

def getSpecName() {
    specPath.split("/")[-1].split(".")[0]
}

def getProjectPath() {
    projectPath.split("/")[-1]
}

def rmDocker() {
    def remove = sh script: "docker rm -f cypress_${getSpecName()}", returnStatus: true
}

stage("Cypress Setup") {
    node("Cypress") {
        rmDocker()
    }
}

stage("Cypress Run") {
    node("Cypress") {
        currentBuild.setDisplayName("${projectPath} - ${getSpecName()}")
        while (failure && retryAmount < numberOfRetries) {
            sh "docker pull dockreg.bluestembrands.com/cypresswithtests:latest"
            if (getSpecName().toLowerCase().contains("auth")) {
                exit_code = sh script:"docker run --name cypress_${getSpecName()} dockreg.bluestembrands.com/cypresswithtests:latest sh -c \"node SQLSite/request.js & cypress run -P ${projectPath} --spec ${specPath} --env RUN=${retryAmount} --config videoCompression=${videoCompression} --reporter /usr/local/lib/node_modules/mochawesome-cypress-bsb --reporter-options \"reportDir=mochawesome-reports/run${retryAmount}/, reportName=mochawesome\"\"", returnStatus: true    
            } else {
                exit_code = sh script:"docker run --name cypress_${getSpecName()} dockreg.bluestembrands.com/cypresswithtests:latest sh -c \"cypress run -P ${projectPath} --spec ${specPath} --env RUN=${retryAmount} --config videoCompression=${videoCompression} --reporter /usr/local/lib/node_modules/mochawesome-cypress-bsb --reporter-options \"reportDir=mochawesome-reports/run${retryAmount}/, reportName=mochawesome\"\"", returnStatus: true  
            }
            failure = exit_code != 0
            try {
                println "/var/docker-mounts/nfs/qa/test-results/${getProjectPath()}-${getSpecName()}/"
                dir("/var/docker-mounts/nfs/qa/test-results/${getProjectPath()}-${getSpecName()}/") {
                    sh "docker cp cypress_${getSpecName()}:/cypress/${projectPath}/mochawesome-reports /var/docker-mounts/nfs/qa/test-results/${getProjectPath()}-${getSpecName()}/${BUILD_ID}"
                }
            } catch (Exception e) {
                println e
                echo "Failed to copy Mochawesome tests"
            }
            rmDocker()
            retryAmount++
        }
    }

    if (failure) {
        currentBuild.result = "FAILURE"
    }
}

当我尝试运行它时,它会抛出以下异常:

我不明白递归调用是在哪里发生的getProjectPath只是做一个标准的分割电话。

我试过把它改成.tokenize()但还是失败了。

值得注意的是,其中不止一个可以同时运行,但是即使隔离运行,也会发生错误。

你能帮我理解一下为什么StackOverflowError会发生吗?

重命名getProjectPath()方法或projectPath变量名。

Groovy文档的这一部分解释了这种行为。可以将其简化为一个示例-一个类似于以下类的类:

class Person {
    String name
}

编译成如下所示:

class Person {
    private String name

    void setName(String name) {
        this.name = name
    }

    String getName() {
        return this.name
    }
}
