Grails 蜡染与圣杯给萨克斯冲突

我正在尝试使用batik和grails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，IntelliJ中出现以下错误：

batik svg dom的pom包括一些其他batik JAR以及xml API和xml-API-ext。我的研究表明，在grails下，xml依赖关系可能会造成麻烦，因为它们在jdk 1.4之外不需要，所以被排除在外

我还尝试使用IntelliJs工具跟踪其他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

我还尝试过grails刷新依赖项，并尝试过删除.grails文件夹，但总是得到相同的结果

有什么想法吗

问题似乎在于Batik包含的xml API版本与现在包含在JDK中的版本冲突。（）所以，这是一个排除“XMLAPI”的问题，正如您已经做的那样。然而，由于Batik的许多JAR对XMLAPI具有可传递的依赖性，因此很难让Grails排除它。以下是最终对我有效的方法：

compile("org.apache.xmlgraphics:fop:0.94",
            "org.apache.xmlgraphics:batik-transcoder:1.7",
            "org.apache.xmlgraphics:batik-codec:1.7",
            "org.apache.xmlgraphics:batik-awt-util:1.7",
            "org.apache.xmlgraphics:batik-bridge:1.7",
            "org.apache.xmlgraphics:batik-dom:1.7",
            "org.apache.xmlgraphics:batik-gvt:1.7",
            "org.apache.xmlgraphics:batik-svg-dom:1.7",
            "org.apache.xmlgraphics:batik-svggen:1.7",
            "org.apache.xmlgraphics:batik-util:1.7",
            "org.apache.xmlgraphics:batik-xml:1.7",
            "org.apache.xmlgraphics:batik-anim:1.7",
            "org.apache.xmlgraphics:batik-css:1.7",
            "org.apache.xmlgraphics:batik-ext:1.7",
            "org.apache.xmlgraphics:batik-js:1.7",
            "org.apache.xmlgraphics:batik-parser:1.7",
            "org.apache.xmlgraphics:batik-script:1.7",
            "org.apache.xmlgraphics:xmlgraphics-commons:1.2",
            "commons-logging:commons-logging:1.0.4",
            "org.apache.avalon.framework:avalon-framework-api:4.3.1",
            "org.apache.avalon.framework:avalon-framework-impl:4.3.1",
            "xalan:xalan:2.6.0",
            "xml-apis:xml-apis-ext:1.3.04"
    ){
        transitive = false
    }

这基本上是我想包括的蜡染罐的白名单。由于transitive=false，将忽略可传递依赖项

然而，我仍然无法让Batik真正发挥作用——似乎还有一个次要问题，即org.apache.Batik.dom.svg.SVGOMDocument缺失，即使在我的war中部署了包含该类的必需JAR

你找到另一个有效的解决方案了吗？

这也让我感到困惑。上面的答案是有效的，但当应用程序使用“grails run app”运行时，会出现“未找到类”异常。使用“grails run war”可以很好地工作。有关原因的更多信息，请参阅。
