Android Studio (3.2.1) Instant Run 不适用于 Jacoco 0.8.2？

Question

我使用 Android Studio 3.2.1 创建了一个简单的 Empty Activity 项目 (Java)。使用 Instant Run 可以正常编译。

但是，当我将 Jacoco 0.8.2 添加到类路径时

dependencies {
    classpath 'com.android.tools.build:gradle:3.2.1'
    classpath 'org.jacoco:org.jacoco.core:0.8.2' //<--Added this
}

编译的时候报错

:app:transformClassesWithInstantRunForDebug 134 ms

禁用即时运行就可以了。这是 Jacoco 或 Android sdk 中的错误吗？

已更新错误说明

Answer 1

作为一种可能的解决方法，您可以尝试使用依赖 ASM 6.0 的 JaCoCo 0.8.1。

Answer 2

在https://github.com/jacoco/jacoco/issues/779#issuecomment-434281431 引用我的回答：

如您所见 - 异常源自 com.android.build.gradle.internal:

Caused by: java.lang.IllegalStateException
  at org.objectweb.asm.tree.analysis.BasicInterpreter.<init>(BasicInterpreter.java:66)
  at com.android.build.gradle.internal.incremental.ConstructorBuilder$1.<init>(ConstructorBuilder.java:127)

  at com.android.build.gradle.internal.transforms.InstantRunTransform.lambda$doTransform$4(InstantRunTransform.java:276)
  at com.android.build.gradle.internal.transforms.InstantRunTransform.lambda$null$5(InstantRunTransform.java:305)

代码 com.android.build.gradle.internal.incremental.ConstructorBuilder.build 这会导致异常 ConstructorBuilder.java:127:

BasicInterpreter interpreter = new BasicInterpreter() {

根据构造函数的Javadoc，这是不正确的 org.objectweb.asm.tree.analysis.BasicInterpreter 抛出 例外在 BasicInterpreter.java:66:

  /**
   * Constructs a new {@link BasicInterpreter} for the latest ASM API version. <i>Subclasses must
   * not use this constructor</i>. Instead, they must use the {@link #BasicInterpreter(int)}
   * version.
   */
  public BasicInterpreter() {
    super(ASM6);
    if (getClass() != BasicInterpreter.class) {
      throw new IllegalStateException();
    }
  }

显然这应该报告给 Android SDK 的开发者 - https://developer.android.com/studio/report-bugs.html

有人可能想知道为什么没有最后一行就不会发生异常

dependencies {
    classpath 'com.android.tools.build:gradle:3.2.1'
    classpath 'org.jacoco:org.jacoco.core:0.8.2'

而且原因类似 https://github.com/jacoco/jacoco/issues/639#issuecomment-355424756 - 类路径中有多个 ASM 版本：

• JaCoCo 0.8.2 需要 ASM 6.2.1 和 org.jacoco:org.jacoco.core:0.8.2 正确声明依赖于 ASM
• exception was added in ASM 6.1
• com.android.build.gradle.internal.incremental.ConstructorBuilder 很可能是开发/使用旧版本的 ASM

为避免此类类路径问题，Android SDK 的开发者可以 重新考虑他们执行 JaCoCo 的方式，例如使用专用的 类加载器。

作为一种可能的解决方法，您可以尝试使用 JaCoCo 0.8.1，这取决于 在 ASM 6.0 上
