接上一遍Load过程的博客来继续 14. Gradle编译其他应用代码流程（三) - Load过程
这一边继续讲Configure过程。
Configure过程源代码
文件路径：
subprojects\core\src\main\java\org\gradle\initialization\DefaultGradleLauncher.java
private void doBuildStages(Stage upTo) {
....
if (stage == Stage.Load) {
// Configure build
buildOperationExecutor.run("Configure build", new Runnable() {
@Override
public void run() {
buildConfigurer.configure(gradle);
if (!gradle.getStartParameter().isConfigureOnDemand()) {
buildListener.projectsEvaluated(gradle);
}
modelConfigurationListener.onConfigure(gradle);
}
});
stage = Stage.Configure;
}
...
}一. 首次看buildConfigurer.configure(gradle)
文件路径：
subprojects\core\src\main\java\org\gradle\configuration\DefaultBuildConfigurer.java
public void configure(GradleInternal gradle) {
...
projectConfigurer.configureHierarchy(gradle.getRootProject());
}文件路径：
subprojects\core\src\main\java\org\gradle\execution\TaskPathProjectEvaluator.java
public class TaskPathProjectEvaluator implements ProjectConfigurer {
...
public void configureHierarchy(ProjectInternal project) {
project.evaluate();
for (Project sub : project.getSubprojects()) {
if (cancellationToken.isCancellationRequested()) {
throw new BuildCancelledException();
}
((ProjectInternal) sub).evaluate();
}
}
}在configureHierarchy里面，首先执行根项目的evaluate()，然后循环执行它的子项目的evaluate()。
就像往下面看：
文件路径：
subprojects\core\src\main\java\org\gradle\api\internal\project\DefaultProject.java
public DefaultProject evaluate() {
getProjectEvaluator().evaluate(this, state);
state.rethrowFailure();
return this;
}subprojects\core\src\main\java\org\gradle\configuration\project\LifecycleProjectEvaluator.java
public void evaluate(ProjectInternal project, ProjectStateInternal state) {
...
state.setExecuting(true);
try {
delegate.evaluate(project, state);
} catch (Exception e) {
addConfigurationFailure(project, state, e);
} finally {
state.setExecuting(false);
state.executed();
notifyAfterEvaluate(listener, project, state);
}
}subprojects\core\src\main\java\org\gradle\configuration\project\ConfigureActionsProjectEvaluator.java
public class ConfigureActionsProjectEvaluator implements ProjectEvaluator {
...
public void evaluate(ProjectInternal project, ProjectStateInternal state) {
for (ProjectConfigureAction configureAction : configureActions) {
configureAction.execute(project);
}
}
}subprojects\core\src\main\java\org\gradle\configuration\project\BuildScriptProcessor.java
public class BuildScriptProcessor implements ProjectConfigureAction {
...
public void execute(ProjectInternal project) {
...
ScriptPlugin configurer = configurerFactory.create(project.getBuildScriptSource(), project.getBuildscript(), project.getClassLoaderScope(), project.getBaseClassLoaderScope(), true);
configurer.apply(project);
...
}
}接下来就会调用到ScriptPluginImpl.apply，这是我们上一遍讲过的。会去应用这个配置文件。具体怎么应用，需要看它生成的class文件。
文件路径在
D:\gradle_jar_cache\caches\3.1-snapshot-1\scripts-remapped\quality_cjfs2g3ij3bqjjsmf9bhahspf\2n69on6v0v04xd0c8c445muqy\dsld7eae713beda1bd9e69f8461da734880\classes
截个class内容的图：
这是因为我们的gradle文件配置了3个plugin
apply plugin: 'checkstyle' apply plugin: 'pmd' apply plugin: 'findbugs'
所以，在configure阶段，它会去解析我们的配置文件，并且去加载我们配置的plugin插件。
以加载pmd插件为例，贴一个调用堆栈：

org.gradle.launcher.bootstrap.ProcessBootstrap.run(ProcessBootstrap.java:37) at org.gradle.launcher.GradleMain.main(GradleMain.java:24)
最后是在ClassloaderBackedPluginDescriptorLocator.findPluginDescriptor方法里面load plugin。
文件路径：
subprojects\core\src\main\java\org\gradle\api\internal\plugins\ClassloaderBackedPluginDescriptorLocator.java
public class ClassloaderBackedPluginDescriptorLocator implements PluginDescriptorLocator {
...
public PluginDescriptor findPluginDescriptor(String pluginId) {
URL resource = classLoader.getResource("META-INF/gradle-plugins/" + pluginId + ".properties");
Exception ex = new Exception("Sandy findPluginDescriptor pluginId: " + pluginId);
ex.printStackTrace();
if (resource == null) {
return null;
} else {
return new PluginDescriptor(resource);
}
}
}它会去找META-INF/gradle-plugins/'pluginid'.properties这个文件。
以pmd为例， pmd的这个配置文件路径是
subprojects\code-quality\src\main\resources\META-INF\gradle-plugins\org.gradle.pmd.properties
内容是 implementation-class=org.gradle.api.plugins.quality.PmdPlugin 它表示pmd插件的描述类是PmdPlugin.java，需要去加载这个类。
二. 加载task
在Configure阶段会load所需要的task，以pmd为例，下面是调用堆栈：

三. buildListener.projectsEvaluated发送通知
文件路径：
subprojects\core\src\main\java\org\gradle\initialization\DefaultGradleLauncher.java
if (!gradle.getStartParameter().isConfigureOnDemand()) {
buildListener.projectsEvaluated(gradle);
}发送projectsEvaluated通知
四. 至此Configure阶段完成
这个阶段主要load了配置文件中的各种plugin；另外它的调用方法是通过加载生成的class文件来进行的。
D:\gradle_jar_cache\caches\3.1-snapshot-1\scripts-remapped\quality_cjfs2g3ij3bqjjsmf9bhahspf\2n69on6v0v04xd0c8c445muqy\dsld7eae713beda1bd9e69f8461da734880\classes
这样不同的配置文件可以用不同的类来执行加载动作，而代码保持一致。
接下来编译进入build阶段。
// After this point, the GradleLauncher cannot be reused stage = Stage.Build;
