grails maven dependency resolution - plugins

Question

I have a grails plugin with following BuildCofnig.groovy
grails.project.class.dir = "target/classes"
grails.project.test.class.dir = "target/test-classes"
grails.project.test.reports.dir = "target/test-reports"
//grails.project.war.file = "target/${appName}-${appVersion}.war"
grails.project.dependency.resolution = {
// inherit Grails' default dependencies
inherits("global") {
}
log "warn" // log level of Ivy resolver, either 'error', 'warn', 'info', 'debug' or 'verbose'
repositories {
grailsPlugins()
grailsHome()
mavenCentral()
mavenLocal()
mavenRepo "http://repository.codehaus.org"
flatDir name: 'lib', dirs: "${userHome}/libs"
}
dependencies {
runtime('mysql:mysql-connector-java:5.1.9')
compile('net.sf.jasperreports:jasperreports:4.0.1') {
excludes 'antlr', 'commons-beanutils', 'commons-collections', 'commons-logging',
'ant', 'mondrian', 'commons-javaflow', 'barbecue', 'xml-apis-ext', 'xml-apis', 'xalan', 'groovy', 'groovy-all', 'hibernate', 'saaj-api', 'servlet-api',
'xercesImpl', 'xmlParserAPIs', 'spring-core', 'bsh', 'spring-beans', 'jaxen', 'barcode4j', 'batik-svg-dom', 'batik-xml', 'batik-awt-util', 'batik-dom',
'batik-css', 'batik-gvt', 'batik-script', 'batik-svggen', 'batik-util', 'batik-bridge', 'persistence-api', 'jdtcore', 'bcmail-jdk14', 'bcprov-jdk14', 'bctsp-jdk14'
}
compile('vomsws:VomsWsClient:1.0')
compile('com.jaxfront:jaxfront-core:1.0',
'com.jaxfront:jaxfront-html:1.0')
compile('freemarker:freemarker:2.3.8')
compile('org.apache.poi:poi:3.6')
compile('commons-net:commons-net:3.0')
compile('commons-httpclient:commons-httpclient:3.1')
}
}
I can pacakge plugin successfully. However when I import this plugin in a fresh Grails project and try to do run-app. I get following exception stack tace:

Compilation error: java.lang.NoClassDefFoundError: org/apache/xerces/xni/parser/XMLParseException
Kind of lost what's the problem here.. Frankly speaking I'm new to this dependency management using Maven and have no clue what so ever.
Your suggestions, recommendations are welcome.

Answer 1

When I see the number of exclusion you set, one should certainly correspond to the class not found .... Search for the good one ;-)
