构建项目时获取源和目标必须不同的错误

我在构建项目时收到此错误。尝试在 android-studio 中添加新库。有没有人有一个想法，基本上我想在这里创建一个新的图书馆。

尝试过的选项：

1. 手动删除构建

2. 使缓存无效/重新启动

3. Gradle 清理构建缓存

4. 构建->清理项目

   但构建失败。

   源 C:\Users\abc\AndroidStudioProjects\Events\app\build\intermediates\cmake\debug\obj\armeabi-v7a\libnative-lib.so 和目标 C:\Users\abc\AndroidStudioProjects\Events\app\build\ middles\cmake\debug\obj\armeabi-v7a\libnative-lib.so 必须不同

我使用的 CMakeLists.txt 也是如此：

# For more information about using CMake with Android Studio, read the
# documentation: https://d.android.com/studio/projects/add-native-code.html

# Sets the minimum version of CMake required to build the native library.

cmake_minimum_required(VERSION 3.4.1)

# Creates and names a library, sets it as either STATIC
# or SHARED, and provides the relative paths to its source code.
# You can define multiple libraries, and CMake builds them for you.
# Gradle automatically packages shared libraries with your APK.

add_library( # Sets the name of the library.
             native-lib

             # Sets the library as a shared library.
             SHARED

             # Provides a relative path to your source file(s).
             native-lib.cpp
        )

add_library (
        testLib
        SHARED
        TestClassesManager.cpp
)
# Searches for a specified prebuilt library and stores the path as a
# variable. Because CMake includes system libraries in the search path by
# default, you only need to specify the name of the public NDK library
# you want to add. CMake verifies that the library exists before
# completing its build.

find_library( # Sets the name of the path variable.
              log-lib

              # Specifies the name of the NDK library that
              # you want CMake to locate.
              log )

# Specifies libraries CMake should link to your target library. You
# can link multiple libraries, such as libraries you define in this
# build script, prebuilt third-party libraries, or system libraries.


target_link_libraries( # Specifies the target library.
                       native-lib

                       # Links the target library to the log library
                       # included in the NDK.
                       ${log-lib}

        )

target_link_libraries(
        testLib

        native-lib
)

如果我更换，错误就会消失

target_link_libraries(
        testLib

        native-lib
)

by

target_link_libraries(
        testLib
    ${log-lib}

)

但我想链接这两个库。但它给出了上述错误。请帮忙。

这是一个weird错误，但感谢您提供简洁的重现项目。事实上，前几天有人向我提到过这一点，但我没有运气重现失败。

我还在调查here https://issuetracker.google.com/158317988，但目前看来，解决方法是运行干净，然后刷新链接的 C++ 项目，然后构建。如果您需要使用“刷新链接的 C++ 项目”按钮，请再次运行 cleanfirst.

已精心挑选了一个修复程序，并将在 4.0.1 中进行修复。
