〇、问题背景
当发生代码合并，触发jenkins流水线，构建成功后将制品发布到maven私服，非常简单的需求。
一、编写过程
1.1 build.gradle
查阅了gradle官方文档: https://docs.gradle.org/current/userguide/publishing_maven.html
我照着抄，相关配置如下:
plugins {
id 'java'
id 'maven-publish'
}
group = 'com.*.*'
// 构建时动态传入版本号
version = project.hasProperty('versionWithCommit') ? project.getProperty('versionWithCommit') : "0.0.5-SNAPSHOT"
sourceCompatibility = '1.8'
repositories {
mavenCentral()
maven {
url "https://maven.demo.cn/repository/maven-releases/"
credentials {
username = project.findProperty("mavenUsername")
password = project.findProperty("mavenPassword")
}
}
}
/**
省略无关配置
**/
test {
useJUnitPlatform()
}
publishing {
publications {
mavenJava(MavenPublication) {
from components.java
}
}
repositories {
maven {
url = "https://maven.demo.cn/repository/maven-releases/"
// 用户名密码从jenkins凭据获取
credentials {
username = project.findProperty("mavenUsername")
password = project.findProperty("mavenPassword")
}
}
}
}
1.2 jenkins pipeline
基本也有现成的可以抄，有效脚本如下:
/**
省略更新代码等无关配置
**/
// 执行测试用例并打包
stage('Build With Test') {
steps {
script {
env.version = getVersion()
withCredentials([usernamePassword
(
credentialsId: 'maven-credencials',
usernameVariable: 'username',
passwordVariable: 'password'
)]){
sh '''
docker run --rm --add-host=127.0.0.1 \
--net=host -P \
-v $PWD/src:/src \
-v /home/ubuntu/jenkins-data/gradle/.gradle:/home/gradle/.gradle \
-v /home/ubuntu/jenkins-data/maven/.m2:/root/.m2 \
-w /src/adaptor/sdk/adaptor gradle:jdk14 \
gradle \
-PversionWithCommit=$version \
-i --stacktrace --watch-fs \
-Dorg.gradle.vfs.verbose=true clean test build --no-build-cache -PbuildNumber=$BUILD_NUMBER -PmavenUsername=$username -PmavenPassword=$password
'''}
junit testResults: 'src/**/build/test-results/test/TEST-*.xml',allowEmptyResults: true
junit testResults: 'src/**/**/build/test-results/test/TEST-*.xml',allowEmptyResults: true
}
}
}
stage('Deploy Artifact') {
steps {
script {
env.version = getVersion()
withCredentials([usernamePassword
(
credentialsId: 'maven-credencials',
usernameVariable: 'username',
passwordVariable: 'password'
)]){
sh '''
docker run --rm --add-host=maven.demo.cn:161.189.43.115 \
--net=host -P \
-v $PWD/src:/src \
-v /home/ubuntu/jenkins-data/gradle/.gradle:/home/gradle/.gradle \
-v /home/ubuntu/jenkins-data/maven/.m2:/root/.m2 \
-w /src/adaptor/sdk/adaptor gradle:jdk14 \
gradle \
-Dorg.gradle.internal.publish.checksums.insecure=true \
-PversionWithCommit=$version \
-i publish --stacktrace --info \
-PbuildNumber=$BUILD_NUMBER \
-PmavenUsername=$username \
-PmavenPassword=$password
echo 'adaptor jars in $PWD/src/adaptor/sdk/adaptor/build/libs:'
ls -al $PWD/src/adaptor/sdk/adaptor/build/libs
'''}
}
}
}
def getVersion(){
def buildVersion = readFile(file: 'build.version')
def version = String.format("%s.%s",buildVersion, env.BUILD_NUMBER)
println('version:' + env.version)
return version
}
二、现象及问题
2.1 现象
简单随意，半小时搞定，git commit & git push，运行一个试试。
结果都是绿的，看起来没啥问题，jenkins 控制台输出如下:
> Task :generateMetadataFileForMavenJavaPublication

Build cache is disabled

但是当我登录nexus maven私服看了之后，我傻眼了，根本没看到我传的包啊😅
2.2 尝试修复
我觉得问题大概出在这里:
> Task :publish
Skipping task ':publish' as it has no actions.
关键的publish任务被skip了，虽然前面的publishMavenJavaPublicationToMavenRepository看起来很正常，但总觉得活没干完。
我在百度、必应、google遨游了两天，尝试过各种奇奇怪怪地修改，还问过我大哥能不能改成maven项目...
最后实在搞不定了，五一假期抱了个大腿，大腿帮我看了一个小时，说:
我觉得你应该已经传成功了，但你nexus账号没权限看...
What? nexus还有这么精细的权限控制？正经功能不优化，净做些花里胡哨的，这么坑人吗😅
三、结论
开工后找权限更高的同事帮忙看了，果然是我nexus没有读权限，nexus的读权限能精确到maven坐标的文件夹🤡
