我有一台Jenkins服务器在现场运行,它使用Jenkins文件管理一个管道,该管道使用并行测试执行器插件在几个代理上运行所有JUnit测试以加快测试速度。我们有一个刀片服务器(比买一个便宜!)并且我们的测试从接近2小时到22分钟加速。 JUnit插件适用于并行测试。
然而,Jacoco Plugin却没有。所以我试图将覆盖文件合并到一个文件,以便Jacoco插件可以发布覆盖结果。 Stash / unstash正在存储源代码,但当我尝试存储不同的Jacoco输出文件以在主服务器上取消它们时,它无法正常工作。任何想法为什么?
这是我的Jenkinsfile:
#!/usr/bin/env groovy
def branch
def hash
node('remote') {
sh 'echo starting'
branch = env.gitlabBranch ?: '**'
echo "Branch: $branch"
checkout([$class: 'GitSCM',

[$class: 'CloneOption', depth: 0, noTags: true, shallow: true, timeout: 180]
],
doGenerateSubmoduleConfigurations: false,
submoduleCfg: [],
userRemoteConfigs: [[credentialsId: 'gitlabLabptop', url: 'git@gitlab.com:protocase/my_project_url.git']]
]
)
hash = sh (script: 'git rev-parse HEAD', returnStdout: true).trim()
### - this stash works fine -###

}
def numBranches = 9
def splits = splitTests count(numBranches)
def branches = [:]
for (int i = 0; i < splits.size(); i++) {
def index = i // fresh variable per iteration; i will be mutated
branches["split${i}"] = {
timeout(time: 125, unit: 'MINUTES') {
node('remote') {
sh 'echo starting a node'
deleteDir()

echo "name: coverage$index, unclude jacoco${index}"
### - this stash appears to work - ###

echo "stashed"
}
}
}
}
parallel branches
def branchIndecis = 0..numBranches
node('master') {
if (currentBuild.result != "ABORTED") {
echo "collecting exec files"
branchIndecis.each {
echo "unstash coverage${it}"
### !!! this unstash causes an error !!! ###
unstash name: "coverage${it}"
echo "make file name"
def coverageFileName = "build/test/jacoco/jacoco${it}.exec"
echo "merge file"
sh "ant -buildfile build-test.xml -Dfile=${coverageFileName} coverageMerge"
}
echo "collected exec files"
step([$class: 'JacocoPublisher',
execPattern:'build/test/jacoco/jacoco.exec',
classPattern: 'build/classes',
sourcePattern: 'src'])
echo "finishing ${branch} - ${hash}"
}
}
我得到的输出是:

注意行

只是我的echo语句,我从脚本的这一部分回显了这个名字:
sh "mv build/test/jacoco/jacoco.exec build/test/jacoco/jacoco${index}.exec"
echo "name: coverage$index, include jacoco${index}"
stash name: "coverage$index", includes: "build/test/jacoco/jacoco${index}.exec"
echo "stashed"
请注意,节点上没有进行实际存储,即使在远程节点上完成,也会将其列为管道。我看到的东西表明存储是在主服务器上完成的,但实际上并不存在于该目录所在的位置。
[[进一步编辑]] - 感谢eis的建议。
master上的jobs / jdesigner / builds / 1639 / stashes /目录包含#.tar.gz文件,其中包含相应的jacoco#.exec文件。当我试着抓住unstash:
try {
unstash name: "coverage${it}"
} catch (error) {
echo "error unstashing: ${error}"
}
我得到的输出是:
collecting exec files
[Pipeline] echo
unstash coverage0
[Pipeline] unstash
[Pipeline] echo
error unstashing: java.io.NotSerializableException: groovy.lang.IntRange
[Pipeline] echo
make file name
答案 0 :(得分:6)
TLDR:这是一个问题,迭代样式导致了这个问题,因为使用的密钥it
不是Serializable
。
让调试变得困难的是,错误消息未正确报告,可能是由于this issue。在代码和“手动”报告中捕获异常修复了该问题。
使用Serializable
键修复了实际问题。
更长的版本:
因为在你的例子中这是有用的:
node('remote') {
### - this stash works fine -###
stash name: 'sources', includes: '**', excludes: '**/.git,**/.git/**'
}
node('remote') {
### - this unstash works fine - ###
unstash 'sources'
}
但这不是:
node('remote') {
### - this stash appears to work - ###
stash name: "coverage$index", includes: "build/test/jacoco/jacoco${index}.exec"
echo "stashed"
}
node('master') {
echo "unstash coverage${it}"
### !!! this unstash causes an error !!! ###
unstash name: "coverage${it}"
}
我最初认为工作的是在远程节点上存储和取消,而非工作的存储在远程节点上,但是您尝试在主节点上取消它(当然不会找到它)
但事实并非如此。根据{{3}},
当您将文件存储在从属文件上时,文件将发送给主文件。 这些文件将存储在相关版本的Job文件夹中 存储文件夹下的文件夹。每个存储将作为tar存储 文件。这些文件将在构建结束时删除。
所以主远程分离不应该有所作为。此外,如果找不到存储,则可this它将失败"No such saved stash ‘" + name + "’
,因为根据see from the sources“捕获此异常时,将报告指定的消息“。这显然没有发生。
相反,应该使用try-catch块进行调试,以找出破坏构建的真正异常。
至于默认情况下没有正确报告的原因,有AbortException javadoc:“在流程结束时序列化错误未在构建日志中正确报告,只有Jenkins日志”。错误报告声称它“固定”但显然只是因为在新版本中,某些测试此行为并未触发问题,因此它可能仍然存在。
如果收到错误消息,可以看到问题是this issue - 当我们传递它时,我们试图序列化一个不可序列化的密钥。
答案 1 :(得分:0)
在Jenkins中使用并行进程时有两种可能性:
您可能尝试在foo$L <- replicate(nrow(foo), sample(foo, 1:foo$K,1))
节点上stash name: "coverage$index", includes: "build/test/jacoco/jacoco${index}.exec"
完成{/ 1}}之前在一个(或多个)进程中解除阻塞
您可能在进程之间存在名称争用。
解释(2):
进程1创建一个名为master
以相同的名称stashed_files
处理2个stashes,然后成功释放。 stashed_files
已删除。
进程1尝试释放stashed_files
。在卸载过程中出现错误,因为进程2删除了stashed_files
。
