Retrolambda：当使用带有 retrolambda 的 lambda 表达式时，Lint 崩溃
Retrolambda: Lint crashes when using lambda expressions with retrolambda
我正在尝试使用 retrolambda along with gradle-retrolambda 插件。一般来说它工作正常，但是当我编译发布时，lint 阶段失败并出现异常：

有什么办法吗？当然，一个微不足道的 work/around 将禁用 lint 检查发布。但我正在寻找解决方案，允许保留 lint。
以下是应用的模块build.gradle:
apply plugin: 'com.android.application'

apt 'com.google.dagger:dagger-compiler:2.0-SNAPSHOT'
provided 'org.glassfish:javax.annotation:10.0-b28'
}
根目录 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()
}
}
有一个 GitHub 问题讨论了这个问题：https://github.com/evant/gradle-retrolambda/issues/96
该问题中的一条评论提到 lint 从未真正使用过 retrolambda，而是使用最新的 lint 版本，现在是 "failing loudly" 而不是简单地跳过其余部分遇到 lambda 时的文件。
考虑到这一点，似乎有两种选择。第一，您可以像问题中提到的那样简单地禁用 lint 。当然，这样做的问题是您将失去 lint 扫描其余代码的好处。第二个选项是回滚你的 lint 版本，这样它就不再是 "failing loudly" 而是简单地跳过检查与 lambda 相关的源代码；这样，lint 仍然可以扫描您的应用程序源代码的其余部分。
根据 GitHub 问题，将 lint 版本从 24.0.1（您可能有不同的版本）回滚到 24.0.0 似乎可以解决问题。您可以在问题中找到此信息（link 在答案开头发布）。
您可以使用带有 lint 的 special lombok version，它不会抱怨 Java 8 个功能。
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'
}
这样你就可以在整个项目中保持 运行 lint，即使使用最新版本的 Android Gradle 插件也是如此。
注意：如果您收到相同的错误，请尝试将上面的配置放入最顶层的build.gradle文件中。到时候应该可以了。

有什么办法吗？当然，一个微不足道的 work/around 将禁用 lint 检查发布。但我正在寻找解决方案，允许保留 lint。
以下是应用的模块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'
}
根目录 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()
}
}
有一个 GitHub 问题讨论了这个问题：https://github.com/evant/gradle-retrolambda/issues/96
该问题中的一条评论提到 lint 从未真正使用过 retrolambda，而是使用最新的 lint 版本，现在是 "failing loudly" 而不是简单地跳过其余部分遇到 lambda 时的文件。
考虑到这一点，似乎有两种选择。第一，您可以像问题中提到的那样简单地禁用 lint 。当然，这样做的问题是您将失去 lint 扫描其余代码的好处。第二个选项是回滚你的 lint 版本，这样它就不再是 "failing loudly" 而是简单地跳过检查与 lambda 相关的源代码；这样，lint 仍然可以扫描您的应用程序源代码的其余部分。
根据 GitHub 问题，将 lint 版本从 24.0.1（您可能有不同的版本）回滚到 24.0.0 似乎可以解决问题。您可以在问题中找到此信息（link 在答案开头发布）。
您可以使用带有 lint 的 special lombok version，它不会抱怨 Java 8 个功能。
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'
}
这样你就可以在整个项目中保持 运行 lint，即使使用最新版本的 Android Gradle 插件也是如此。
注意：如果您收到相同的错误，请尝试将上面的配置放入最顶层的build.gradle文件中。到时候应该可以了。
