1、安装JDK
cd /data/softs
tar xf openjdk-11.0.0.1_linux-x64_bin.tar.gz -C /data/server/
ln -s /data/server/jdk-11.0.0.1 /usr/local/java
cat << 'CAT_END' >> /etc/profile
export JAVA_HOME=/usr/local/java
export LS_JAVA_HOME=/usr/share/logstash/jdk
export PATH=$JAVA_HOME/bin:$PATH
CAT_END
source /etc/profile
java -version
2、安装Maven
2.1、下载软件
# 官网地址
https://maven.apache.org/download.cgi
curl -O https://dlcdn.apache.org/maven/maven-3/3.9.2/binaries/apache-maven-3.9.2-bin.tar.gz
2.2、安装软件
tar xvf apache-maven-3.9.2-bin.tar.gz -C /data/server/
ln -s /data/server/apache-maven-3.9.2 /usr/local/maven
cat << 'CAT_END' > /etc/profile.d/maven.sh
export MAVEN_HOME=/usr/local/maven
export PATH=$PATH:$MAVEN_HOME/bin
CAT_END
source /etc/profile.d/maven.sh
2.3、更换maven仓库为阿里云
# vi /usr/local/maven/conf/settings.xml
<mirrors>
...
<mirror>
<id>alimaven</id>
<name>aliyun maven</name>
<url>http://maven.aliyun.com/nexus/content/groups/public/</url>
<mirrorOf>central</mirrorOf>
</mirror>
...
</mirrors>
# mirror配置一个即可
2.4、查看mvn版本
# mvn -v
Apache Maven 3.9.2 (c9616018c7a021c1c39be70fb2843d6f5f9b8a1c)
3、Jenkins配置maven
3.1、Jenkins增加maven环境变量
3.2、配置全局JDK
3.3、安装maven插件
Maven IntegrationVersion
Pipeline Maven IntegrationVersion
3.4、安装插件完后，会多出一个maven项目
4、Jenkins Java maven项目构建
4.1、准备代码
4.1.1、测试代码下载
sonar插件提供了一个代码库
github:https://github.com/SonarSource/sonar-examples
软件包下载：https://github.com/SonarSource/sonar-examples/archive/master.zip
# 这里使用java maven测试代码
4.1.2、上传至gitlab
4.2、创建maven项目
4.3、配置git
4.4、指定pod.xml位置
4.5、立即构建
root@localhost:~/.jenkins/workspace/my-maven# ll java-maven-simple/target/
