Ant是一个Apache基金会下的跨平台的构件工具,可以实现自动构建和部署,大多数用于JAVA环境中的软件开发

ANT流程
jar包这个部分步骤是为下面编译增量包做准备的,因为增量包导出的增量文件,它依赖于整个项目的其他代码,如果没有这些代码的支持是编译不通过。然而又不能直接通过diff得到增量的class,所以只能导出增量文件后,通过引用全部工程的代码的class再进行编译即可

环境:
   centos 7.2
   jdk version 1.7.0_79
   ant version 1.9.9

如果报这个错,说明是服务器上目前的JDK版本不正确

The Apache Ant team currently maintains two lines of development. The 1.9.x releases require Java5 at runtime and 1.10.x requires Java8 at runtime. Both lines are based off of Ant 1.9.7 and the 1.9.x releases are mostly bug fix releases while additional new features are developed for 1.10.x. We recommend using 1.10.x unless you are required to use versions of Java prior to Java8 during the build process.
Currently, Apache Ant 1.9.9 and 1.10.1 are the best available versions, see the release notes.

ANT+Jenkins

ant_jenkins_plugin
“Jenkis”— “系统管理”— “Global Tool Configuration”— “Ant”
ant_jenkins
ant_jenkins
ant_jenkins
ant_jenkins

这里没有ANT项目就不跑Jenkins了哈
