我正在尝试使用带有 grails 的 batik 在服务器上将一些 SVG 内容渲染为 PNG。
当我将依赖项添加到 BuildConfig 然后告诉 IntelliJ 加载更改时，我在 IntelliJ 中收到以下错误：

Grails clean 给出了类似的结果。
BuildConfig.groovy 包含以下内容：
grails.project.dependency.resolution = {
// inherit Grails' default dependencies
inherits("global") {
excludes 'slf4j-log4j12', 'xml-apis', 'xalan', 'xml-apis-ext', 'commons-logging', 'commons-io'
}
log "warn" // log level of Ivy resolver, either 'error', 'warn', 'info', 'debug' or 'verbose'
checksums true // Whether to verify checksums on resolve
repositories {
inherits true // Whether to inherit repository definitions from plugins
grailsPlugins()
grailsHome()
grailsCentral()
mavenCentral()
}
dependencies {
compile "org.jadira.usertype:usertype.jodatime:1.9"
compile "org.imgscalr:imgscalr-lib:4.0"
compile("org.apache.xmlgraphics:batik-svg-dom:1.7")
{
excludes 'batik-xml', 'batik-dom', 'commons-javaflow',
'avalon-framework-api', 'avalon-framwork-impl',
'batik-css', 'batik-gvt', 'batik-script',
'slf4j-log4j12', 'xml-apis', 'xml-apis-ext', 'log4j', 'xercesImpl', 'xalan',
'antlr', 'commons-beanutils', 'commons-collections', 'commons-logging', 'xmlParserAPIs',
'ant', 'mondrian', 'groovy-all', 'saaj-api', 'servlet-api', 'spring-core', 'bsh',
'spring-beans', 'jaxen', 'persistence-api', 'jdtcore', 'bcmail-jdk16', 'bcprov-jdk16',
'bctsp-jdk16', 'bcmail-jdk14', 'bcprov-jdk14', 'bctsp-jdk14', 'xmlbeans'
}
}
batik-svg-dom 的 pom 包括其他一些 batik jar 以及 xml-apis 和 xml-apis-ext。我的研究表明，xml 依赖项在 grails 下可能会导致问题，并且由于在 jdk 1.4 之后不需要它们，因此它们已被排除在外。
我还尝试使用 IntelliJs 工具追踪其他 org.xml.sax.Locator 实例，但找到的唯一实例位于：/Applications/Dev/grails-2.1.0/lib/org.apache.ant/ant-launcher /jars/ant-launcher-1.8.2.jar!/org/apache/tools/ant/launch/Locator.class
我也尝试过 grails refresh-dependencies 并尝试删除 .grails 文件夹，但我总是得到相同的结果。
请问有什么想法吗？
