Question

我正在尝试将Android应用的支持库依赖关系从27.0.2升级到27.1.0。执行此操作并尝试组装应用程序时，编译失败。

对于kotlin数据绑定我正在使用：kapt "com.android.databinding:compiler:3.0.1"

对于我正在使用的kotlin：implementation "org.jetbrains.kotlin:kotlin-stdlib-jre7:1.2.30"

这是尝试编译时产生的堆栈跟踪

我认为问题是kotlin，考虑到KaptTask.kt:124中捕获了编译异常。但我无法确定在我的应用程序中需要更改哪些内容才能成功编译。

非常感谢任何帮助！提前谢谢。

Answer 1

因此编译错误是由于支持库中的更改（在这种情况下，围绕kotlin中@IntDef的更改不再需要传入Long，而是需要Int）。

我原本无法找到此编译错误，因为它隐藏在Android Studio抛出的100多个数据绑定错误中。（我在我的应用中大量使用数据绑定）

要解决此问题，我将gradle日志中显示的最大错误次数添加到我的应用程序的gradle文件中：

// Works for both java and kotlin
kapt {
    javacOptions {
        // Increase the max count of errors from annotation processors.
        // Default is 100.
        option("-Xmaxerrs", 1000)
    }
}

这增加了BOTH kotlin和java的最大错误数，而我见过的另一个实现没有。如图所示：

// Only works for java
allprojects {
    gradle.projectsEvaluated {
        tasks.withType(JavaCompile) {
            options.compilerArgs << "-Xmaxerrs" << "1000"
        }
    }
}

这只会增加java的最大错误数，而不是kotlin。只是一个FYI。

无论如何，随着错误计数的增加，我能够在底部找到非常有用的编译错误，这实际上是问题所在。这些很容易修复。

Answer 2

也许您想尝试

implementation org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.2.30

来自https://kotlinlang.org/docs/reference/using-gradle.html

由于`kapt`，Android支持库Bump 27.1.0无法编译
