我有一个我正在创建的机器人,它可以从IRC通道获取输入,以便为运行时使用的机器人创建新类。但是,当它尝试编译该类时,会在类名称中导致“标识符预期”错误。但是,如果我输入的类与使用模板的机器人创建的类相同,则编译时没有问题。以下是此过程使用的3种方法:
//Create basic command
public static int writeBasicCommand(String trigger, String output, boolean edit) {
int success = 0, existenceError = 1, unknownError = 2;
try {
String filePath = "C:/commands/" + trigger + ".java"; //Location for new class
File file = new File(filePath);
//Check if command exists
if (file.exists()) {
if(!edit) {
return existenceError;
}
} else if(edit) {
return existenceError;
}
//Grab and modify template
String template = readFile("C:/template.txt");
String namedCom = template.replace("--COMMANDNAME--", trigger);
String content = namedCom.replace("--COMMANDRESULT--", "\"" + output + "\"");
//Write command
WriteFile(content, file, false);
if (Compile(filePath)==true) {
System.out.println("Done");
return success;
} else {
return unknownError;
}
} catch (IOException e) {
e.printStackTrace();
return unknownError;
}
}
//Compile new commands
public static boolean Compile(String fileToCompile) {
System.setProperty("java.home", "C:\\Program Files\\Java\\jdk1.7.0_11");
JavaCompiler compiler = ToolProvider.getSystemJavaCompiler();
int compilationResult = compiler.run(null, null, null, fileToCompile);
if(compilationResult == 0) {
System.out.println("Compilation is successful");
return true;
} else {
System.out.println("Compilation Failed");
if ((new File(fileToCompile).exists())) {
new File(fileToCompile).delete();
}
return false;
}
}
//Write to a file
public static boolean WriteFile(String fileContents, File destination, boolean append) {
try {
// if file doesnt exist, then create it
if (!destination.exists()) {
destination.createNewFile();
}
FileWriter fw = new FileWriter(destination.getAbsoluteFile(), append);
BufferedWriter bw = new BufferedWriter(fw);
bw.write(fileContents);
bw.close();
fw.close();
return true;
} catch (IOException e) {
e.printStackTrace();
return false;
}
}
