我下载了DITA OpenToolkit 1.8并尝试构建演示。
ant -f build_demo.xml
它一直运行到mapref任务，它会抛出错误，如下所示。 现在，错误表明错误，显然是错误的ICONST值。但如果之前没有人真正测试过这些样本，我会非常惊讶，因为无论你选择哪种输出格式都会出现错误，所以这很明显。
因此我在想，运行构建时可能缺少任何配置或参数吗？

答案 0 :(得分：1)
我无法在Windows上重现此问题，至少。
您有double-checked your CLASSPATH还是尝试过使用Saxon而不是Xalan？我实际上认为DITA-OT放弃了对Xalan when all XSLT stylesheets were converted to XSLT 2.0的支持。
编辑：啊，我的坏。 XSLT 2.0提交不包含在1.8版本中。
