Answer 1

org/apache/xml/serialize/OutputFormat是一个Xerces类…在系统中搜索xerces*.jar。这个文件存在吗?它在您的类路径中吗?

Answer 2

您的类路径缺少

所需的jar

org/apache/xml/serialize/OutputFormat

检查你的类路径中是否有xercesImpl.jar

EDIT:

您可以通过在ant编译目标中包含所需的jar并将所有所需的jar放在lib文件夹中来设置。

<target name="compile" depends=""   description="compile the java source files">  
 <javac srcdir="." destdir="${build}">  
    <classpath>  
        <fileset dir="${lib}">  
            <include name="**/*.jar" />  
        </fileset>  
    </classpath>  
</javac>
