在多模块项目中使用Gradle的Android AspectJ

有没有办法将图书馆模块中的aspectJ切入点应用到整个项目?这意味着我需要附加库来存在项目,它必须拦截来自主项目的方法调用及其所有依赖项(也包括Android SDK方法) 现在我尝试通过build.gradle中的脚本执行此操作:

android.libraryVariants.all { variant ->

variant.javaCompile.doLast {
// Find the android.jar and add to iajc classpath
    def androidSdk = android.adbExe.parent + "/../platforms/" + android.compileSdkVersion +    "/android.jar"
    println 'Android SDK android.jar path: ' + androidSdk

    def iajcClasspath;
    iajcClasspath = androidSdk;


    project.rootProject.allprojects.each { proj ->
        if (proj.configurations.hasProperty("compile"))
            iajcClasspath += ":" + proj.configurations.compile.asPath
        // handle aar dependencies pulled in by gradle (Android support library and etc)
        tree = fileTree(dir: "${proj.buildDir}/exploded-aar", include: '**/classes.jar')
        tree.each { jarFile ->
            iajcClasspath += ":" + jarFile
        }
    }
    println 'Classpath for iajc: ' + iajcClasspath
    ant.taskdef(resource: "org/aspectj/tools/ant/taskdefs/aspectjTaskdefs.properties", classpath: configurations.ajc.asPath)
    println 'ajctPath : ' + configurations.ajc.asPath.toString()
    println 'aspectPath : ' + configurations.aspects.asPath.toString()
    println 'inpath : ' + configurations.ajInpath.asPath.toString()
    ant.iajc(
            source: sourceCompatibility,
            target: targetCompatibility,
            fork: true,
            destDir: "${project.buildDir}/classes/${variant.dirName}",
            aspectPath: configurations.aspects.asPath,
            inpath: configurations.ajInpath.asPath,
            sourceRootCopyFilter: "**/*.java",
            classpath: iajcClasspath
    ) {
        sourceroots {
            android.sourceSets.main.java.srcDirs.each {
                pathelement(location: it.absolutePath)
            }
// Build config file
            pathelement(location: "${project.buildDir}/source/buildConfig/${variant.dirName}")
// Android resources R.***
            pathelement(location: "${project.buildDir}/source/r/${variant.dirName}")
        }
    }
}
}

但是切入点仅适用于从此模块调用的方法。此外,即使我将脚本移动到main build.gradle,并将android.libraryVariants替换为android.applicationVariants,切入点也不适用于附加的.jar库和模块,但是处理gradle依赖项(例如compile&#39) ; com.googlecode.mp4parser:isoparser:例如1.0.1')。

如果没有办法用AspectJ做这个,也许还有其他方法可以拦截项目库中所有项目中的方法调用?最重要的是,主模块代码中不应该有任何更改,只需在库中。

在阅读了来自ant ajcTask的文档后,我终于使用我的gradle插件GradleAndroidAspectJPlugin实现了。

我使用iajc classpath和inpath属性指定哪些类(jar)将作为类路径编译,或者将从aspectj编译器重新编译。

def aopTask = project.task("compile${buildTypeName}AspectJ") {
                doFirst {
                    project.configurations.aspectsInPath.each {
                        aspectsInPaths.add(it);
                        aspectsInPathsAbsolute.add(it.absolutePath);
                    }
                }

                doLast {
                    ant.taskdef(
                            resource: "org/aspectj/tools/ant/taskdefs/aspectjTaskdefs.properties",
                            classpath: project.configurations.aspectjTaskClasspath.asPath
                    )
                    ant.iajc(
                            source: project.android.compileOptions.sourceCompatibility,
                            target: project.android.compileOptions.targetCompatibility,
                            fork: "true",
                            destDir: variant.javaCompile.destinationDir,
                            bootClasspath: project.android.bootClasspath.join(File.pathSeparator),
                            inpathDirCopyFilter: "java/**/*.class"
                    ) {
                        classpath {
                            variant.javaCompile.classpath.each {
                                if (!aspectsInPathsAbsolute.contains(it)) {
                                    pathElement(location: it)
                                }
                            }
                        }
                        inpath {
                            pathElement(location: copyDir)
                            aspectsInPaths.each {
                                if (!it.name.startsWith("aspectjrt")) {
                                    pathElement(location: it)
                                }
                            }
                        }
                    }
                }
            }
