【已解决】Ming/MSYS下运行FOP出错：Unable to start FOP， java.lang.RuntimeException: fop.jar not found in directory

【问题】

MingW的MSYS环境下，运行FOP，结果出错了：

【解决过程】

1. 尝试去将FOP_HOME从：

E:\Dev_Root\docbook\tools\fop-1.0

改为MSYS的路径

/E/Dev_Root/docbook/tools/fop-1.0

然后重启MingW再去测试，结果更加错误的了：

2. 看了半天，感觉还是先要把之前在这里：

【终极解决】fop错误：Exception in thread "main" java.lang.NoClassDefFoundError:org/apache/xmlgraphics/image/loader/ImageContext 的终极解决办法，即cygpath有bug，转换路径出错，导致部分路径被截断

对于fop的改动再改回来，即把：

#LCP_TEMP=`cygpath –path –unix "$LOCALCLASSPATH"`

# for cygpath has bug, so use follow workaround

# edit by admin AT crifan DOT com

LCP_TEMP=`cygpath –path –$format "$LOCALCLASSPATH"`

LCP_TEMP=`cygpath –path –unix "$LCP_TEMP"`

再改回：

LCP_TEMP=`cygpath –path –unix "$LOCALCLASSPATH"`

# for cygpath has bug, so use follow workaround

# edit by admin AT crifan DOT com

#LCP_TEMP=`cygpath –path –$format "$LOCALCLASSPATH"`

#LCP_TEMP=`cygpath –path –unix "$LCP_TEMP"`

看看结果如何。结果却是问题依旧。

3. 最后，还是感觉让java去执行/E/xxx的MSYS路径，明显不太多，所以还是改回去：

把FOP_HOME的/E/Dev_Root/docbook/tools/fop-1.0改回E:\Dev_Root\docbook\tools\fop-1.0

不过，倒也可以先试试：

E:/Dev_Root/docbook/tools/fop-1.0

的效果如何。

结果无意中，竟然就正常执行了，真是很无语：

4. 回头再去刚刚才的改动，之所以可以让其正常工作，主要是里面的所有的路径中的分隔符，都是Unix中的斜杠，而非开始的斜杠和反斜杠的混合体。

【总结】

MingW/MSYS环境下，运行FOP出错Unable to start FOP， java.lang.RuntimeException: fop.jar not found in directory的

原因是FOP_HOME的路径设置有误。

解决办法是：

把FOP_HOME从

从windows（cmd）类型的路径：

E:\Dev_Root\docbook\tools\fop-1.0

改为Unix类型的路径：

E:/Dev_Root/docbook/tools/fop-1.0

如此，FOP（在MingW的环境下）就可以正常识别对应的路径了。

注意，也不能改为MingW的路径：

/E/Dev_Root/docbook/tools/fop-1.0

否则还是会出现另外的错误”找不到或无法加载主类 org.apache.fop.cli.Main “的。
