解决Jenkins2.15在JDK11下遇到的问题

下载安装包

wget https://pkg.jenkins.io/redhat-stable/jenkins-2.150.1-1.1.noarch.rpm

安装

rpm -ivh jenkins-2.150.1-1.1.noarch.rpm

添加依赖

1. 由于jdk11删除了不少包，所以根据官网指示，需要添加一些依赖的jar包：

• jaxb-api-2.3.0.jar (save as jaxb-api.jar)
• jaxb-core-2.3.0.1.jar (save as jaxb-core.jar)
• jaxb-impl-2.3.0.1.jar (save as jaxb-impl.jar)
• javax.activation v.1.2.0 (save as javax.activation.jar)

详见官网： https://jenkins.io/blog/2018/12/14/java11-preview-availability/

2. 将四个包下载到 /usr/lib/jenkins 下和jenkins.war放一起比较合适

修改jenkins配置文件

1. 打开配置文件

vim /etc/sysconfig/jenkins

2. 找到"JENKINS_JAVA_OPTIONS"，修改为如下：

JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -p /usr/lib/jenkins/jaxb-api.jar:/usr/lib/jenkins/javax.activation.jar --add-modules java.xml.bind,java.activation -cp /usr/lib/jenkins/jaxb-core.jar:/usr/lib/jenkins/jaxb-impl.jar"

3. 找到"JENKINS_ARGS"，修改为如下：

JENKINS_ARGS="--enable-future-java"

安装字体

sudo yum install -y fontconfig
