I found I may need JDK 10 for Jenkins to support my projects.
Website to download JDK10
https://jdk.java.net/java-se-ri/10
wget https://download.java.net/openjdk/jdk10/ri/openjdk-10+44_linux-x64_bin_ri.tar.gz -P install/
I follow this step install openJDK 10 on Docker
#install the software
RUN yum -y update
RUN yum install -y freetype
RUN      mkdir -p /tool/
#install /tool/jdk-10
ADD        install/openjdk-10+44_linux-x64_bin_ri.tar.gz /tool/
WORKDIR /tool/
ENV JAVA_HOME /tool/jdk-10
ENV PATH="${JAVA_HOME}/bin:${PATH}"
But it seems not working for jenkins.
I directly run this command with my oracle jdk, it works fine.
> java --add-modules java.xml.bind -jar install/jenkins.war --enable-future-java
We can always download the Oracle JDK here
https://www.oracle.com/technetwork/java/javase/downloads/java-archive-javase10-4425482.html
Here is the start.sh
#!/bin/sh -ex
cd /tool/
java -Duser.home=/var/jenkins_home --add-modules java.xml.bind -jar jenkins.war \
     --enable-future-java
Here is the Dockerfile
#Set Up Jenkins CI
#Prepre the OS
FROM centos:7
MAINTAINER Yiyi Kang <[e-mail]>
#install the software
RUN yum -y update
RUN yum install -y freetype
RUN yum install -y git
RUN yum install -y wget make
RUN      mkdir -p /tool/
#install /tool/jdk-10
ADD        install/jdk-10.0.2_linux-x64_bin.tar.gz /tool/
WORKDIR /tool/
ENV JAVA_HOME /tool/jdk-10.0.2
ENV PATH="${JAVA_HOME}/bin:${PATH}"
#install jenkins
ADD        install/jenkins.war /tool/
#start the application
EXPOSE  8080 50000
RUN     mkdir -p /app/
ADD     start.sh /app/
WORKDIR /app/
CMD    [ "./start.sh" ]
After that, I directly configure
JDK Name: jdk10.0.2
       JAVA_HOME: /tool/jdk-10.0.2
Git       Name: Git1.8
Gradle Name: Gradle5.1.1 install automatically
Ant      Name: Ant1.10.5 install automatically
Maven Name: MAVEN3.6.0 install automatically
Set Up TimeZone for Jenkins
Lis the timezone in America
> sudo timedatectl list-timezones | grep America
Austin is the same as Chicago
> sudo timedatectl set-timezone America/Chicago
> date
Fri Jan 25 09:16:08 CST 2019
Add this to start.sh in Jenkins
#!/bin/sh -ex
cd /tool/
java -Duser.home=/var/jenkins_home \
     -Duser.timezone=America/Chicago \
     --add-modules java.xml.bind \
     -jar jenkins.war \
     --enable-future-java

If any permission issue happens
> sudo chmod -R 777 ./jenkins_home
Check every 5 minutes
