以编程方式调用ant编译源文件（不用xml)，代码如下:
javac compiler = new javac（);
compiler.setproject（new project（));
file destfile = new file（buildfillepath);
path srcpath = new path（compiler.getproject（), srcfilepath);
compiler.setsrcdir（srcpath);
compiler.setdestdir（destfile);
compiler.setcompiler（ "extjavac ");
try {
compiler.ＥＸＥＣute（);
}
catch （buildexception e) {
e.printstacktrace（);
}
报错如下：
