Retrolambda：Retrolambdaでラムダ式を使用するとLintがクラッシュする
gradle-retrolambda プラグインとともに retrolambda を使用しようとしています。一般的には問題なく動作しますが、リリース用にコンパイルすると、lintステージが例外で失敗します。

それについて何かすることはありますか？もちろん、簡単な回避策は、リリースのlintチェックを無効にすることです。しかし、私はlintを維持できる解決策を探しています。
以下はアプリのモジュールbuild.gradle：
apply plugin: 'com.Android.application'
apply plugin: 'me.tatarka.retrolambda'
apply plugin: 'com.neenbedankt.Android-apt'
configurations {
apt
}
Android {
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
compileSdkVersion 22
buildToolsVersion "21.1.2"
defaultConfig {
minSdkVersion 10
targetSdkVersion 22
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled true
shrinkResources true
proguardFiles getDefaultProguardFile('proguard-Android-optimize.txt'), 'proguard-rules.pro'
}
}
}
repositories {
maven{
url 'https://oss.sonatype.org/content/repositories/snapshots/'
}
}
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.Android.support:appcompat-v7:22.0.0'
compile 'com.jakewharton:butterknife:6.1.0'
compile 'com.google.dagger:dagger:2.0-SNAPSHOT'
compile 'de.greenrobot:eventbus:2.4.0'
retrolambdaConfig 'net.orfjackal.retrolambda:retrolambda:1.8.1'
apt 'com.google.dagger:dagger-compiler:2.0-SNAPSHOT'
provided 'org.glassfish:javax.annotation:10.0-b28'
}
ルートbuild.gradle：
buildscript {
repositories {
jcenter()
}
dependencies {
classpath 'com.Android.tools.build:gradle:1.1.0'
classpath 'com.neenbedankt.gradle.plugins:Android-apt:1.4'
classpath 'me.tatarka:gradle-retrolambda:2.5.0'
}
}
allprojects {
repositories {
jcenter()
}
}
特別なlombokバージョン をlintと共に使用できます。lintは、Java 8の機能については駄目です。
buildscript {
repositories {
jcenter()
...
}
dependencies {
classpath 'com.Android.tools.build:gradle:<version>'
classpath 'me.tatarka:gradle-retrolambda:<version>'
classpath 'me.tatarka.retrolambda.projectlombok:lombok.ast:0.2.3.a2'
}
// Exclude the version that the Android plugin depends on.
configurations.classpath.exclude group: 'com.Android.tools.external.lombok'
}
このようにして、Android Gradleプラグインの最新バージョンであっても、プロジェクト全体でlintを実行し続けることができます。
注：同じエラーが発生する場合は、上記の構成を一番上に配置してみてくださいbuild.gradleファイル。それならうまくいくはずです。
この問題を説明するGitHubの問題があります： https://github.com/evant/gradle-retrolambda/issues/96
問題のコメントの1つには、lintが実際にレトロラムダで機能したことはなく、最新のlintバージョンでは、ファイルの残りを単にスキップするのではなく、「大声で失敗する」ことが記載されていますラムダが見つかりました。
これを考慮して、2つのオプションがあるようです。 1つは、質問で述べたようにlintを無効にするだけです。もちろん、これの問題は、コードの残りの部分をスキャンするlintの利点を失うことです。 2番目のオプションは、lintバージョンをロールバックして、「大音量で失敗する」のではなく、ラムダ関連のソースのチェックをスキップすることです。このようにして、lintは残りのアプリケーションソースコードをスキャンできます。
GitHubの問題によると、lintのバージョンを24.0.1（別のバージョンの可能性があります）から24.0.0にロールバックすると、問題が解決するようです。この情報は問題（回答の最初に掲載されているリンク）にあります。
