Gradel源碼入門二

在org.gradle.launcher.bootstrap  ProcessBootstrap.java中

private void runNoExit(String mainClassName, String[] args) throws Exception {//new DefaultModuleRegistry, 做了大量初始化的工作，查找classpath結構
        ClassPathRegistry classPathRegistry = new DefaultClassPathRegistry(new DefaultClassPathProvider(new DefaultModuleRegistry()));
        ClassLoaderFactory classLoaderFactory = new DefaultClassLoaderFactory();//找到Ant相關的jar包， 分析jar包裏面的 META-INF/MANIFEST.MF 屬性
        ClassPath antClasspath = classPathRegistry.getClassPath("ANT");//找gradle相關的包，分析gradle-launcher-2.x.jar 包裏面的gradle-launcher-classpath.properties
        ClassPath runtimeClasspath = classPathRegistry.getClassPath("GRADLE_RUNTIME");
        ClassLoader antClassLoader = classLoaderFactory.createIsolatedClassLoader(antClasspath);
        ClassLoader runtimeClassLoader = new MutableURLClassLoader(antClassLoader, runtimeClasspath);
        Thread.currentThread().setContextClassLoader(runtimeClassLoader);
        Class<?> mainClass = runtimeClassLoader.loadClass(mainClassName);
        Object entryPoint = mainClass.newInstance();
        Method mainMethod = mainClass.getMethod("run", String[].class);
        mainMethod.invoke(entryPoint, new Object[]{args});
    }

mainMethod   

org.gradle.launcher.bootstrap.EntryPoint 的run函數

這是由於

public class Main extends EntryPoint
