Groovy Grape处理依赖性解析 [英] Groovy Grape dealing with dependency resolution
问题描述
我试图在groovy脚本中使用 org.xhtmlrenderer:core-renderer:R8pre2 ，但出现链接错误:
I am trying to use org.xhtmlrenderer:core-renderer:R8pre2 in a groovy script, but I get a Linkage error:
Caught: java.lang.LinkageError: loader constraint violation in interface
itable initialization: when resolving method
"org.apache.xerces.dom.NodeImpl.getOwnerDocument()Lorg/w3c/dom/Document;"
the class loader (instance of org/codehaus/groovy/tools/RootLoader) of the
current class, org/apache/xerces/dom/NodeImpl, and the class loader (instance of
<bootloader>) for interface org/w3c/dom/Node have different Class objects for
the type getOwnerDocument used in the signature
我已经在Google上搜索了很多，并找到了很多类似这样的答案:
I've already googled a lot and found a lot of answer like these:
与JavaSE 6内部冲突的XercesImpl实施.两者都需要...该怎么办?
因此，一种解决方案可能是使用Java的 endorsed 机制来解决冲突，但是我想使我的脚本独立于这种变通方法".该脚本应该立即可用.
So, one solution could be to use javas endorsed mechanism to resolve the conflict, but I would like to make my script independent from such a "workaround". The script should run out of the box.
接下来我要尝试的是排除像这样的正确依赖项
Next thing I was giving a try was to exclude the right dependency like this
@Grapes([
@Grab('org.xhtmlrenderer:core-renderer:R8pre2'),
@GrabExclude('xml-apis:xml-apis')
])
但没有成功...
有什么想法吗?
PS:这是产生错误的脚本:
PS: here is the script which creates the error:
@Grapes([
@Grab('org.xhtmlrenderer:core-renderer:R8pre2'),
])
import org.w3c.dom.Document
import javax.xml.parsers.DocumentBuilder
import javax.xml.parsers.DocumentBuilderFactory
def dbf = DocumentBuilderFactory.newInstance()
DocumentBuilder builder = dbf.newDocumentBuilder()
Document doc = builder.parse(new ByteArrayInputStream("<html></html>".getBytes()))
推荐答案
感谢@dmahapatro，我检查了配置，发现很久以前我在{usrhome}/.groovy中放了一些jar.删除了这些内容，现在一切都变得很迷人...
Thanx to @dmahapatro, I checked my configuration and found that I dropped some jars in {usrhome}/.groovy a long time ago. Removed these and now everything work like a charm...
