杰克和Android - Lambda运行时失败直到干净的构建

Question

看似随机,Android Studio安装的apk已损坏.它通常以lambdas为中心(但每次都是不同的).我正在使用Jack编译和所有内容的最新版本(最后列出).问题一直存在,直到我做了一个干净的构建(然后一切都很好).间歇性故障是一种新现象.Jack和Java 8功能暂时保持稳定.不幸的是,我无法确定在片状失败开始之前发生了什么变化.

示例代码:

private static final Ordering<Foo> ORDER_BY_FOO =
    Ordering.natural().onResultOf(Foo::getId);

实际问题分配(在Guava代码中):

ByFunctionOrdering(Function<F, ? extends T> function, Ordering<T> ordering) {
  this.function = checkNotNull(function);  // <-- Fails
[...]
class ByFunctionOrdering<F, T> extends Ordering<F> {
  final Function<F, ? extends T> function;

示例运行时异常:

• Android Studio/gradle构建工具2.2.2
• Gradle 2.14.1
• buildToolsVersion 25.0.0
• sourceCompatibility/targetCompatibility JavaVersion.VERSION_1_8
• compileSdkVersion/targetSdkVersion 24

Answer 1

我认为这是构建工具 25.0.0 和 25.0.1 中的错误。恢复到 24.0.3 解决了我的这个问题。

更新 更新到 后com.android.tools.build:gradle:2.2.3，我用构建工具 v25.0.1 度过了一个完整的工作日，没有构建错误。
