java fop_java – 未找到类FOP

嗨所以我试图使用FOP将xml文件转换为pdf并且我继续遇到错误,现在我有错误

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/xmlgraphics/io/ResourceResolver

at org.apache.fop.apps.FopConfParser.(FopConfParser.java:122)

at org.apache.fop.apps.FopFactory.newInstance(FopFactory.java:132)

at run.ExampleFO2PDF.main(ExampleFO2PDF.java:62)

我在构建路径中有FOP库以及xmlgraphics和commons日志和Avalon框架

这是我试图运行的代码

} finally {

out.close();
