我想从代码编译现有的Android项目。 如果在我的控制台中输入ant debug，它会起作用，但如果我尝试从我的代码构建它，它会失败。以编程方式编译Android项目
我尝试运行脚本using the following code：
private static boolean runAntScript(String scriptName) {
File buildFile = new File(scriptName);
Project project = new Project();
DefaultLogger myLogger = new DefaultLogger();
project.setUserProperty("ant.file", buildFile.getAbsolutePath());
myLogger.setErrorPrintStream(System.err);
myLogger.setOutputPrintStream(System.out);
myLogger.setMessageOutputLevel(Project.MSG_VERBOSE);
project.addBuildListener(myLogger);
try {
project.fireBuildStarted();
project.init();
ProjectHelper helper = ProjectHelper.getProjectHelper();
project.addReference("ant.projectHelper", helper);
helper.parse(project, buildFile);
project.executeTarget("debug");
project.fireBuildFinished(null);
} catch (Exception e) {
project.fireBuildFinished(e);
return false;
}
return true;
}

如果我添加：
project.setProperty("key.store", "/home/axi/.android/debug.keystore");
project.setProperty("ant.home", "/home/axi/Downloads/apache-ant-1.8.3/bin");
project.setProperty("ant.version", "Apache Ant(TM) version 1.8.3 compiled on February 26 2012");
现在的问题是：
