以编程方式编译Android项目

标签： android ant compilation project

我想从代码中编译现有的Android项目。 如果只是在我的控制台中键入ant debug它可以工作，但是如果我尝试从我的代码构建它就会失败。

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：

将所有（可能不是全部都需要）Android Sdk和Ant libs以及tools.jar添加到它工作的类路径后:)。
