Question

我想在我的android项目中同时使用evant/gradle-retrolambda和RoboBinding/RoboBinding。

将RoboBinding添加到项目时，您可以选择使用RoboBinding/RoboBinding-aspectj-plugin与AspectJ一起使用。但是，每当我打开它时，我的代码中的lambda表达式都会产生这个编译错误：

Error:error at (no source information available)
/mnt/FCEE58DAEE588F30/AndroidstudioProjects/SpeechACall/app/src/main/java/com/voicesense/personality_profiling_dialer/GcmRegistrationHandler.java:1:0::0 The type java.lang.invoke.MethodHandles cannot be resolved. It is indirectly referenced from required .class files
FAILURE: Build failed with an exception.

* What went wrong:
Execution failed for task ':app:compileDebugAspectJ'.
> The type java.lang.invoke.MethodHandles cannot be resolved. It is indirectly referenced from required .class files

* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

这是我的build.gradle文件

here是一个压缩的Android Studio项目，可用于重现（包含相关的build.gradle文件和无法编译的lambda表达式。）

经过一番调查后，我发现它与AspectJ不兼容Java 8。我相信Java 8 Compatiblity/Update AspectJ · Issue #22 · JakeWharton/hugo和Java 8 not supported · Issue #6 · uPhyca/gradle-android-aspectj-plugin有同样的问题。有什么建议吗？

我使用retrolambda制作了自己的插件支持aspectj。 GradleAndroidAspectJPlugin

当项目使用retrolambda时。在编译retrolamda之后，你必须使用ant iajc重新编译类。

    project.configurations {
        aspectjTaskClasspath
        aspectsInPath
    }

    project.repositories {
        mavenCentral()
    }

    def aspectjVersion = '1.8.5';
    project.dependencies {
        //AspectJ
        aspectjTaskClasspath "org.aspectj:aspectjtools:$aspectjVersion"
        compile "org.aspectj:aspectjrt:$aspectjVersion"
    }

    project.afterEvaluate {
        project.android.applicationVariants.all { variant ->

            def buildTypeName = variant.name.capitalize()
            def hasRetrolambda = project.plugins.hasPlugin('me.tatarka.retrolambda')

            def copyDir = new File("${project.buildDir.absolutePath}/copyClasses")
            if (copyDir.exists()) {
                copyDir.deleteDir()
            }
            copyDir.mkdirs()

            def copyClassTask = project.task("copy${buildTypeName}Classes", type: Copy) {
                from variant.javaCompile.destinationDir
                into copyDir
                doLast {
                    variant.javaCompile.destinationDir.deleteDir()
                    variant.javaCompile.destinationDir.mkdirs()
                }
            }

            def aspectsInPaths = [];
            def aspectsInPathsAbsolute = [];
            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)
                                }
                            }
                        }
                    }
                }
            }
            aopTask.dependsOn(copyClassTask);

            def filterPreDexTask = project.task("filter${buildTypeName}PreDex") {
                doLast {
                    def finalPreDexJars = []
                    project.tasks["preDex${buildTypeName}"].inputFiles.each {
                        if (it.name.startsWith("aspectjrt") ||
                                !aspectsInPathsAbsolute.contains(it.absolutePath)) {
                            finalPreDexJars.add(it)
                        }
                    }
                    project.tasks["preDex${buildTypeName}"].inputFiles = finalPreDexJars
                }
            }
            project.tasks["preDex${buildTypeName}"].dependsOn(filterPreDexTask)



            if (hasRetrolambda) {
                project.tasks["compileRetrolambda$buildTypeName"].finalizedBy(aopTask)
            } else {
                project.tasks["compile${buildTypeName}Java"].finalizedBy(aopTask)
            }

        }
    }
