android-studio - 构建项目时获取源和目标必须是不同的错误

Question

我在构建项目时收到此错误。试图在 android-studio 中添加一个新库。有没有人基本上有一个想法，我正在尝试在这里创建一个新库。

尝试的选项:

手动删除构建

缓存失效/重启

Gradle 清理构建缓存

构建->清理项目

但是构建失败了。

源 C:\Users\abc\AndroidStudioProjects\Events\app\build\intermediates\cmake\debug\obj\armeabi-v7a\libnative-lib.so 和 objective-c :\Users\abc\AndroidStudioProjects\Events\app\build\中间件\cmake\debug\obj\armeabi-v7a\libnative-lib.so 必须不同

CMakeLists.txt 我正在使用它:

# 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
)

经过

target_link_libraries(
        testLib
    ${log-lib}

)

但我想链接两个库。但它给出了上述错误。请帮忙。

这是一个奇怪的错误，但感谢您提供简洁的重现项目。实际上前几天有人向我提到了这一点，但我没有运气重现失败。

我还在调查here ，但现在似乎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，请再次先运行 clean。

已精心挑选了一个修复程序，并将在 4.0.1 中发布。
