dipendenze librerie transitive batik

Question

Sto usando Gradle per ottenere Batik (una libreria SVG) e fuori dalla scatola, mancano alcune librerie transitive. Quale dovrei inserire?

ho già cercato di ottenere il xml-API o Xerces lib

Gradle: codice

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: errore

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(); 

Esecuzione:

Ho scaricato il codice sorgente di batik-1.8 e la classe mancante fa parte del codice sorgente ufficiale.

Ho compilato le librerie con ant maven-artifacts e controllato tutti i file jar per vedere quale ha ottenuto quello org.w3c.dom package. L'ho trovato in batik-ext-1.8.

Questo barattolo è stato scaricato da Gradle, ma è presente solo una directory Manifest; non classi. Vedi http://central.maven.org/maven2/org/apache/xmlgraphics/batik-ext/1.8/batik-ext-1.8.jar

Quindi il barattolo non è stato costruito correttamente quando viene spinto a fare pratica.

ho aperto un bug report qui: https://issues.apache.org/jira/browse/BATIK-1120
