Bert Van der Heyden commented on MJAVADOC-136:
----------------------------------------------
I had exactly the same problem and it has indeed nothing to do with UmlGraphDoc
which is a wonderful tool I must admit.
I assume this is a Windows XP issue which has to do with the fact that
Runtime.getRuntime().exec("some command") always fails.
Anyway, I have found a cure: By building a bat file in the temp directory
containing the correct command and using the ProcessBuilder class afterwards to
run that bat file, it works like a charm. It took me a while to find that out,
but it was worth every second. Those generated UML diagrams are just very cool.
And here is the code for in UmlGraphDoc
{{
private static void runGraphviz(String outputFolder, String packageName,
String name, RootDoc root) {
File dotFile = new File(outputFolder, (new StringBuilder()).append(
packageName.replace(".",
"/")).append("/").append(name).append(
".dot").toString());
File pngFile = new File(outputFolder, (new StringBuilder()).append(
packageName.replace(".",
"/")).append("/").append(name).append(
".png").toString());
File mapFile = new File(outputFolder, (new StringBuilder()).append(
packageName.replace(".",
"/")).append("/").append(name).append(
".map").toString());
try {
String[] dotCmdArray=new String[] { "dot", "-Tcmapx", "-o",
"\"" + mapFile.getAbsolutePath() + "\"",
"-Tpng", "-o",
"\"" + pngFile.getAbsolutePath() + "\"",
"\"" + dotFile.getAbsolutePath() + "\""};
StringBuffer dotCmd=new StringBuffer();
for (int i=0;i<dotCmdArray.length;i++){
dotCmd.append(dotCmdArray[i]);
dotCmd.append(" ");
}
String cmd=dotCmd.toString();
String tmpBatFile=System.getenv("temp") + "/rundot.bat";
try{
BufferedWriter out=new BufferedWriter(new
FileWriter(tmpBatFile));
out.write("echo off\n");
out.write(cmd);
out.close();
}catch(IOException e){}
List<String> command = new ArrayList<String>();
command.add(tmpBatFile);
command.add("/A");
ProcessBuilder builder = new ProcessBuilder(command);
Map<String, String> environ = builder.environment();
builder.directory(new File(System.getenv("temp")));
final Process process = builder.start();
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line;
while ((line = br.readLine()) != null) {
//System.out.println(line);
}
//System.out.println("Program terminated!");
} catch (Exception e) {
e.printStackTrace();
}
}
}}
