解决Jenkins运行ant脚本编译项目报错Unable to load annotation processing manager org.eclipse.jdt.internal.compiler.apt.dispatch.BatchAnnotationProcessorManager from classpath.

在进行Jenkins+ant+tomcat编译项目自动化的时候，运行过程中会出现报错：

Unable to load annotation processing manager org.eclipse.jdt.internal.compiler.apt.dispatch.BatchAnnotationProcessorManager from classpath.

原因是用ant编译时通过eclipsejdt去编译的，是依赖eclipse或myeclipse里面的插件的，所以需要把eclipse或myeclipse的插件里面的某些jar文件放到ant安装目录的lib文件夹内
在eclipse安装目录搜索jdt，找到
org.eclipse.jdt.annotation_1.1.100.v20160418-1457.jar    （注意：下滑杠后面的部分因安装版本不一样是不一样的，只要找下滑杠前面部分跟我写出来的一致就行）
org.eclipse.jdt.annotation_2.1.100.v20170511-1408.jar
org.eclipse.jdt.apt.core_3.5.50.v20170920-0950.jar
org.eclipse.jdt.apt.ui_3.5.0.v20170505-1107.jar
org.eclipse.jdt.compiler.apt_1.3.60.v20171129-1553.jar
org.eclipse.jdt.compiler.tool_1.2.51.v20171122-1403.jar
org.eclipse.jdt.core_3.13.101.v20180215-0725.jar
org.eclipse.jdt.debug.ui_3.8.52.v20180104-1240.jar
下图我红色圈出来的可能没有圈完全

复制完成如下图

 复制完成之后再运行就ok了

下面附上我的ant脚本：
