BUILD FAILED build.xml:324: Problem: failed to create task or type replaceregexp Cause: the class org.apache.tools.ant.taskdefs.optional.ReplaceRegExp was not found. This looks like one of Ant's optional components. Action: Check that the appropriate optional JAR exists in -D:\java\tool\apache-ant-1.7.0\lib -C:\Users\username\.ant\lib -a directory added on the command line with the -lib argument Do not panic, this is a common problem. The commonest cause is a missing JAR. This is not a bug; it is a configuration problem
错误原因是使用的功能replaceregexp对应的java类不存在,这是ant中可选的组件, 下载ant-nodeps-1.7.0.jar包到ant目录下的lib目录,然后添加到ANT_CLASSPATH中
set ANT_CLASSPATH=%ANT_HOME%\lib\ant-nodeps-1.7.0.jar;
