[root@localhost /]# which java
/usr/local/iron/jdk1.8.0_191/bin/java

#JDK的安装路径和Jenkins 默认的JDK路径不一致
#建立软连接
ln -s /usr/local/iron/jdk1.8.0_191/jdk/bin/java /usr/bin/java

#如果多版本，可以使用下面的命令更新
[root@localhost /]# update-alternatives --install /usr/bin/java java /usr/local/iron/jdk1.8.0_191/bin/java 300
[root@localhost /]# update-alternatives --install /usr/bin/javac javac /usr/local/iron/jdk1.8.0_191/bin/javac 300
[root@localhost /]# update-alternatives --install /usr/bin/jar jar /usr/local/iron/jdk1.8.0_191/bin/jar 300
[root@localhost /]# update-alternatives --install /usr/bin/javah javah /usr/local/iron/jdk1.8.0_191/bin/javah 300
[root@localhost /]# update-alternatives --install /usr/bin/javap javap /usr/local/iron/jdk1.8.0_191/bin/javap 300
[root@localhost /]# update-alternatives --config java

[root@localhost /]# which java
/usr/bin/java

 

或者修改jenkins配置文件

vi /etc/rc.d/init.d/jenkins

类似如下修改：

candidates="
/etc/alternatives/java
/usr/lib/jvm/java-1.8.0/bin/java
/usr/lib/jvm/jre-1.8.0/bin/java
/usr/lib/jvm/java-1.7.0/bin/java
/usr/lib/jvm/jre-1.7.0/bin/java
/usr/lib/jvm/java-11.0/bin/java
/usr/lib/jvm/jre-11.0/bin/java
/usr/lib/jvm/java-11-openjdk-amd64
/usr/bin/java
/usr/local/iron/jdk1.8.0_191/bin/java #把自己配置的目录加进去
