signavio-core-components ant build-all-in-one-war failed

最近搞了下signavio-core-components项目，网址是http://code.google.com/p/signavio-core-components

执行ant build-all-in-one-war或者ant build-and-deploy-all-in-one-war-to-tomcat

BUILD FAILED
D:\signavio\build.xml:64: The following error occurred while executing this line
D:\signavio\editor\build.xml:118: Java returned: 2

研究了一下是因为编码问题，ant文件调用了editor/build.xml。其中有

<concat destfile='${build}/oryx.debug.js'>...</concat>

这个命令是合并文件，但是源文件中的scripts/Core/SVG/label.js是utf-8格式的，而其他是ansi格式的，这个utf-8文件转成ansi会出现乱码。因此修改为

<property name="charset" value="utf-8"/><concat destfile='${build}/oryx.debug.js' encoding="${charset}" outputencoding="${charset}">这样合并后的文件没有问题，但是YUICompressor压缩还是有问题，到官网下载最新的2.4.7，放到lib目录，将其中的yuicompressor-2.4.2.jar修改为yuicompressor-2.4.7.jar
<java dir="${build}" jar="${root}/lib/yuicompressor-2.4.7.jar" fork="true" failonerror="true" output='${compress.temp}'>解决办法同样PO在了项目issue中，参见<a href="http://code.google.com/p/signavio-core-components/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Type%20Status%20Priority%20Milestone%20Owner%20Summary&groupby=&sort=&id=29">http://code.google.com/p/signavio-core-components/issues/detail?can=2&start=0&num=100&q=&colspec=ID%20Type%20Status%20Priority%20Milestone%20Owner%20Summary&groupby=&sort=&id=29</a>
