我有一个Geoscript库，可以读取上载的shapefile，然后将其转换为WKT。当我将库上传到lib目录时，此方法有效，但是当我从Maven中将其拉入库时，会出现sax冲突。有人知道解决方案吗？
这是错误
|错误执行脚本时出错错误清除:违反了加载器约束:在解决重写的方法“org.apache.tools.ant.helper.ProjectHelper2 $ RootHandler.setDocumentLocator(Lorg / xml / sax / Locator;)V”时，类加载器(org /当前类org / apache / tools / ant / helper / ProjectHelper2 $ RootHandler的当前类的codehaus / groovy / grails / cli / support / GrailsRootLoader)及其父类(super class)加载器(实例为)，其类型为andler.setDocumentLocator的Class对象不同。 (Lorg / xml / sax / Locator;)签名中使用的V(注意:堆栈跟踪已被过滤。使用--verbose查看整个跟踪。)
最佳答案
这是由Grails错误(即GRAILS-9331)体现的。您应该能够排除有问题的库，但是Grails忽略了这一点。 Grails修复程序(尚不可用)实际上并未解决此问题，它仅在加载类时忽略org.xml。这是一个间接修复，似乎仍然会错误加载xml-apis库。理想的解决方案是:
compile ('org.geoscript:geoscript-groovy:1.0-SNAPSHOT') {
excludes "xml-apis","xml-apis-ext","xercesImpl","xalan"
}
Grails错误阻止了此工作。
我将排除列表和依赖项加载到Gradle中，并生成了1.0-SNAPSHOT的依赖项列表。此白名单可以代替“org.geoscript:geoscript-groovy:1.0-SNAPSHOT”

非常冗长，但可以在Grails 2.1.0中正常运行
