也许现在回答这个问题有点晚了,但是经过几天的研究,我找到了一种在github中为每个PR创建多个作业的方法。我展示的代码适用于github企业版,但是只需稍微调整url和git命令,也可以在一般的github(bitbucket)上很好地工作。
主线存储库需要有一个文件,我称之为PRJob.groovy,其中包含:
import groovy.json.JsonSlurper
gitUrl = GIT_URL
repoRestUrl = "${GITHUB_WEB_URL}/repos/${project}/${repo}"
def getJSON(url) {
def conn = (HttpURLConnection) new URL(url).openConnection()
conn.setRequestProperty("Authorization", "token ${OAUTH_TOKEN}");
return new JsonSlurper().parse(new InputStreamReader(conn.getInputStream()))
}
def createPipeline(name, description, branch, prId) {
return pipelineJob(name) {
delegate.description description
if (ENABLE_TRIGGERS == 'true') {
triggers {
cron 'H H/8 * * *'
scm 'H/5 * * * *'
}
}
quietPeriod(60)
environmentVariables {
env 'BRANCH_NAME', branch
env 'PULL_REQUEST', prId
env 'GITHUB_WEB_URL', GITHUB_WEB_URL
env 'OAUTH_TOKEN', OAUTH_TOKEN
env 'PROJECT', project
env 'REPO', repo
}
definition {
cpsScm {
scriptPath "Jenkinsfile"
scm {
git {
remote {
credentials "jenkins-ssh-key"
delegate.url gitUrl
if (prId != "") {
refspec "+refs/pull/${prId}/*:refs/remotes/origin/pr/${prId}/*"
}
}
delegate.branch branch
}
}
}
}
}
}
def createPRJobs() {
def prs = getJSON("${repoRestUrl}/pulls?state=open")
if (prs.size() == 0) {
def mergedPrs = getJSON("${repoRestUrl}/pulls?state=closed")
if (mergedPrs.size() == 0) {
throw new RuntimeException("No pull-requests found; auth token has likely expired")
}
}
prs.each { pr ->
def id = pr.get("number")
def title = pr.get("title")
def fromRef = pr.get("head")
def fromBranchName = fromRef.get("ref")
def prRepo = fromRef.get("repo")
def repoName = prRepo.get("name")
def prHref = pr.get("url")
createPipeline("${repo}-PR-${id}-${fromBranchName}",
"${prHref} Pull Request ${id}: ${title}", "origin/pr/${id}/head", id)
}
}
createPRJobs()
这将为每个PR创建1个jenkins作业。
这依赖于项目具有可用于运行管道作业的Jenkinsfile。示例Jenkinsfile如下所示:
commitId = null
repoRestUrl = "${GITHUB_WEB_URL}/repos/${PROJECT}/${REPO}"
try{
stage('Install and Tests') {
runTest("Hello")
}
notify_github 'success'
}catch (Exception e) {
notify_github 'failure'
print e
throw e
}
def runTest(String someDummyVariable) {
node {
checkout scm
sh 'git clean -qdf'
if (env.PULL_REQUEST == ""){
sh 'git rev-parse --verify HEAD > commit.txt'
} else {
sh "git rev-parse refs/remotes/origin/pr/${env.PULL_REQUEST}/head^{commit} > commit.txt"
}
commitId = readFile 'commit.txt'
echo commitId
sh 'rm -f commit.txt'
sh 'echo "Hello World!!!!!"'
}
}
def http_post(url, rawJson) {
def conn = (HttpURLConnection) new URL(url).openConnection()
conn.setRequestProperty("Authorization", "token ${OAUTH_TOKEN}");
conn.doOutput = true
conn.requestMethod = "POST"
conn.setRequestProperty("Content-Type", "application/json")
def wr = new OutputStreamWriter(conn.getOutputStream());
wr.write(rawJson);
wr.close()
def code = conn.getResponseCode()
if (code < 200 || code >= 300){
println 'Failed to post to ' + url
def es = conn.getErrorStream();
if (es != null) {
println es.getText()
}
}
}
def notify_github(state) {
http_post(
"${repoRestUrl}/statuses/${commitId}",
"""
{ "state": "${state}",
"target_url": "${env.BUILD_URL}",
"description": "Build Pipeline",
"context": "Build Pipeline"
}
"""
)
}
希望这对某些人有所帮助。
