While using xerces (2.9.1) Grails throw an exception:

There is an easy way to reproduce this error:

enable maven repository - mavenCentral()

and add dependencies: runtime 'xerces:xercesImpl:2.9.1'

run grails run-war: an exception is thrown:

Hi Graeme

Issue has been solved :

I installed jarscan (https://jarscan.dev.java.net/servlets/ProjectDocumentList) and found that there's a version of xml-apis that is bundled with Grails Drools plugin

nic@host> cd $HOME/.grails
nic@host> java -jar /Users/nicolas/Downloads/jarscan/jarscan.jar SAXParseException
.....................................................................
+1.2-M4/projects/test/plugins/drools-0.3/lib/xml-apis-1.0.b2.jar
1.2-M4/projects/test/plugins/drools-0.3/lib/xml-apis-1.0.b2.jar/org/xml/sax/SAXParseException.class
----------------------------------------------
Scanned archives: 70
Errors: 0

I deleted xml-apis-1.0.b2 from the plugin lib folder and now it works.

I'll inform the Drools plugin author, thanks Graeme

FYI

  1. Grails version: 1.2-M4
  2. JVM version: 1.6.0_15

Hi, I did some investigation and it seems that it is similar problem to http://jira.codehaus.org/browse/GROOVY-2303 .
I removed xml-apis dependency for xalan and xerces from my pom definition and it's seams that it help.

I have to remove other dependency now...

I think it will become a big problem eventually... If you have any idea how to solve it or you can solve it in more general way that would be great.

I am also experiencing this problem. It seems related to the closed issue http://jira.codehaus.org/browse/GRAILS-5337.

I have not seen the problem under Maven, only with Ivy. At this point I have been unable to prevent Ivy from loading xml-api, and my only solution has been to place an empty xml-api.jar in the ivy repository.

I would really appreciate an update on this issue. Thanks,

– Harlan

I had this issue when resolving some axis2/rampart dependencies in order to consume webservices. Xerces and xml-apis were subdependencies of the axis2/rampart jars in the maven repository. My current solution to prevent xerces and xml-apis is to use the Grails Ivy excludes command.

build ("axis2/rampart dependencies") {
excludes "xercesImpl", "xmlParserAPIs", "xml-apis";
}

Thanks Brian, that did the job as a work around. I had tried something similar earlier but had the wrong Ivy syntax (not so familiar with it), so thanks for the example.

The issues remain rather inconvenient though. When using a Maven pom for dependency management (pom=true in grails config) and running Maven operations everything works, but running a Grails command with the same configuration results in an error. So the work around comes down to maintaining the pom for dependencies (so I can use Maven as part of our standard build) and maintaining the ivy dependency management (so Intellij with work and a developer has the option of running standard Grails commands).

Similar problem occurs when using org.codehaus.groovy.modules.http-builder (http://groovy.codehaus.org/modules/http-builder/home.html)

The following fixed the problem:
test('org.codehaus.groovy.modules.http-builder:http-builder:0.5.1') { excludes 'xml-apis', 'xercesImpl' }

I encountered a similar problem and after following a note on GRAILS-5337, was able to resolve it by deleting my Ivy cache (~/.ivy2/cache). Hope that helps.

Experiencing this problem when performing run-app on a Grails 1.3.7 app with Apache POI 3.8. Excluding xmlbeans from the dependencies seemed to work:

dependencies {
compile('org.apache.poi:poi-ooxml:3.8-beta3') { excludes "xmlbeans" }
}

I excluded xml-apis in my pom.xml and now the war file is getting created successfully.
But i'm getting java.lang.NoClassDefFoundError: org/w3c/dom/ElementTraversal during the runtime.
If i include xml-api.jar inside the WEB-INF/lib directory after the creation of war file, the error disappeared.
Unfortunately, i can't do this manually. I'm using Grails 1.3.7.
(Even including xml-apis with "runtime" dependency in pom.xml doesn't help )
Any work around for this is highly appreciated.
