java - 蜡染布传递库依赖性

我正在使用Gradle获取Batik(一个SVG库)，并且开箱即用，它缺少一些可传递的库。我应该放哪一个？

我已经尝试获取xml-api或Xerces lib

Gradle :

version = 1.0
mainClassName = 'com.foilen.svgexporter.SvgExporter'

sourceCompatibility = '1.8'
targetCompatibility = '1.8'

dependencies {
    compile 'args4j:args4j:2.32'
    compile 'org.apache.xmlgraphics:batik-rasterizer:1.8'
}

Java代码:

PNGTranscoder transcoder = new PNGTranscoder();
InputStream in = new FileInputStream("character_man_black.svg");
TranscoderInput input = new TranscoderInput(in);
OutputStream ostream = new FileOutputStream("character_man_black.png");
TranscoderOutput output = new TranscoderOutput(ostream);
transcoder.transcode(input, output);

// Flush and close the output.
ostream.flush();
ostream.close();
in.close();

执行错误:

最佳答案

我下载了batik-1.8的源代码，缺少的类是官方源代码的一部分。

我使用ant maven-artifacts编译了这些库，并检查了所有jar文件，看看哪个得到了org.w3c.dom package。
我在batik-ext-1.8中找到了它。

Gradle正在下载该jar，但是那里只有一个Manifest目录。不是类(class)。
参见http://central.maven.org/maven2/org/apache/xmlgraphics/batik-ext/1.8/batik-ext-1.8.jar

因此，将 jar 插入行家时， jar 的构建不正确。

我在这里打开了一个错误报告:https://issues.apache.org/jira/browse/BATIK-1120
