一、jenkins配置

在jenkins里面配置好ant版本

构建完成后执行shell脚本重启tomcat

二、build.xml配置

1. 从官网http://ant.apache.org/bindownload.cgi获取最新的tar包。
2. 上传至服务器目录，解压tar包即可

　　tar –xvf   apache-ant-1.9.2-bin.tar

注：使用javacc编译存在一些条件无法编译的情况，可以使用eclipse的编译器jdt进行编译。找到

　　jdtCompilerAdapter.jar

　　org.eclipse.jdt.compiler.tool_1.0.100.v_B79_R37x.jar

　　org.eclipse.jdt.core_3.7.3.v20120119-1537.jar

　　org.eclipse.jdt.debug.ui_3.6.1.v20111006_r372.jar

　　上传至ant目录的lib下。在build.xml申明下使用jdt即可

　　<property name="build.compiler"value="org.eclipse.jdt.core.JDTCompilerAdapter">
