Gradle 工具源碼不是gradle wrapper 源碼

安裝android studio之后，Gradle 工具被緩存到 user/.gradle/cache/module-2/下面，不同的AS,緩存具體路徑還不一樣。

對于gradle-2.3.3.jar 源碼：

Context類代碼：

package com.android.build.api.transform;import java.io.File; import org.gradle.api.logging.LoggingManager;public abstract interface Context {public abstract LoggingManager getLogging();public abstract File getTemporaryDir();public abstract String getPath(); }

QualifiedContent代碼：

package com.android.build.api.transform;import java.io.File; import java.util.Set;public abstract interface QualifiedContent {public abstract String getName();public abstract File getFile();public abstract Set<ContentType> getContentTypes();public abstract Set<? super Scope> getScopes();public static abstract interface ContentType{public abstract String name();public abstract int getValue();}public static enum DefaultContentTypeimplements QualifiedContent.ContentType{CLASSES(1), RESOURCES(2);private final int value;private DefaultContentType(int value){this.value = value;}public int getValue(){return this.value;}}public static abstract interface ScopeType{public abstract String name();public abstract int getValue();}public static enum Scopeimplements QualifiedContent.ScopeType{PROJECT(1), PROJECT_LOCAL_DEPS(2), SUB_PROJECTS(4), SUB_PROJECTS_LOCAL_DEPS(8), EXTERNAL_LIBRARIES(16), TESTED_CODE(32), PROVIDED_ONLY(64);private final int value;private Scope(int value){this.value = value;}public int getValue(){return this.value;}} }

JarInput代碼：

package com.android.build.api.transform;public abstract interface JarInputextends QualifiedContent {public abstract Status getStatus(); }

Transform類：

package com.android.build.api.transform;import com.google.common.collect.ImmutableList; import com.google.common.collect.ImmutableMap; import com.google.common.collect.ImmutableSet; import java.io.File; import java.io.IOException; import java.util.Collection; import java.util.Map; import java.util.Set;public abstract class Transform {public abstract String getName();public abstract Set<QualifiedContent.ContentType> getInputTypes();public Set<QualifiedContent.ContentType> getOutputTypes(){return getInputTypes();}public abstract Set<? super QualifiedContent.Scope> getScopes();public Set<? super QualifiedContent.Scope> getReferencedScopes(){return ImmutableSet.of();}@Deprecatedpublic Collection<File> getSecondaryFileInputs(){return ImmutableList.of();}public Collection<SecondaryFile> getSecondaryFiles(){return ImmutableList.of();}public Collection<File> getSecondaryFileOutputs(){return ImmutableList.of();}public Collection<File> getSecondaryDirectoryOutputs(){return ImmutableList.of();}public Map<String, Object> getParameterInputs(){return ImmutableMap.of();}public abstract boolean isIncremental();@Deprecatedpublic void transform(Context context, Collection<TransformInput> inputs, Collection<TransformInput> referencedInputs, TransformOutputProvider outputProvider, boolean isIncremental)throws IOException, TransformException, InterruptedException{}public void transform(TransformInvocation transformInvocation)throws TransformException, InterruptedException, IOException{transform(transformInvocation.getContext(), transformInvocation.getInputs(), transformInvocation.getReferencedInputs(), transformInvocation.getOutputProvider(), transformInvocation.isIncremental());} }

TransformInput類代碼：

package com.android.build.api.transform;import java.util.Collection;public abstract interface TransformInput {public abstract Collection<JarInput> getJarInputs();public abstract Collection<DirectoryInput> getDirectoryInputs(); }

TransformInvocation代碼：

package com.android.build.api.transform;import java.util.Collection;public abstract interface TransformInvocation {public abstract Context getContext();public abstract Collection<TransformInput> getInputs();public abstract Collection<TransformInput> getReferencedInputs();public abstract Collection<SecondaryInput> getSecondaryInputs();public abstract TransformOutputProvider getOutputProvider();public abstract boolean isIncremental(); }

TransformOutputProvider代碼：

package com.android.build.api.transform;import java.io.File; import java.io.IOException; import java.util.Set;public abstract interface TransformOutputProvider {public abstract void deleteAll()throws IOException;public abstract File getContentLocation(String paramString, Set<QualifiedContent.ContentType> paramSet, Set<? super QualifiedContent.Scope> paramSet1, Format paramFormat); }

看到 gradle.jar 定義了加載plugin 方法，沒有看到加載到哪些plugin,沒有看到加載?com.android.application plugin
