I'm building a Unity project for Android on a Windows VM and, when I run Azure DevOps pipelines, I get the following error message:

* What went wrong:
Execution failed for task ':unityLibrary:BuildIl2CppTask'.
> Warning: Could not find file [Path here]\jniLibs\arm64-v8a\libil2cpp.dbg.so to copy.

It happens when I run a task:

  - bash: |
      chmod +x '$(System.ArtifactsDirectory)\...path...\il2CppOutputProject\IL2CPP\build\deploy\netcoreapp3.1'
      chmod +x gradlew
      ./gradlew assembleRelease --stacktrace --info
      ./gradlew generateAPIDoc

At first, it seemed to me that /libil2cpp.dbg.so won't be found as it is moved to /libil2cpp.so. On the VM, in unityLibrary/build.gradle, the following piece of code is present (it is not a part of code on repo):

def BuildIl2Cpp(String workingDir, String configuration, String architecture, String abi, String[] staticLibraries) {
    def commandLineArgs = []
    commandLineArgs.add("--compile-cpp")
    commandLineArgs.add("--platform=Android")
    commandLineArgs.add("--architecture=" + architecture)
    commandLineArgs.add("--outputpath=" + workingDir + "/src/main/jniLibs/" + abi + "/libil2cpp.so")
    commandLineArgs.add("--libil2cpp-static")
    commandLineArgs.add("--baselib-directory=" + workingDir + "/src/main/jniStaticLibs/" + abi)
    commandLineArgs.add("--configuration=" + configuration)
    commandLineArgs.add("--dotnetprofile=unityaot-linux")
    commandLineArgs.add("--profiler-report")
    commandLineArgs.add("--profiler-output-file=" + workingDir + "/build/il2cpp_"+ abi + "_" + configuration + "/il2cpp_conv.traceevents")
    commandLineArgs.add("--print-command-line")
    commandLineArgs.add("--generatedcppdir=" + workingDir + "/src/main/Il2CppOutputProject/Source/il2cppOutput")
    commandLineArgs.add("--cachedirectory=" + workingDir + "/build/il2cpp_"+ abi + "_" + configuration + "/il2cpp_cache")
    commandLineArgs.add("--tool-chain-path=" + android.ndkDirectory)
    staticLibraries.eachWithIndex {fileName, i->
        commandLineArgs.add("--additional-libraries=" + workingDir + "/src/main/jniStaticLibs/" + abi + "/" + fileName)
    }
    def executableExtension = ""
    if (org.gradle.internal.os.OperatingSystem.current().isWindows())
        executableExtension = ".exe"
    exec {
        executable workingDir + "/src/main/Il2CppOutputProject/IL2CPP/build/deploy/il2cpp" + executableExtension
        args commandLineArgs
        environment "ANDROID_SDK_ROOT", getSdkDir()
    }
    delete workingDir + "/src/main/jniLibs/" + abi + "/libil2cpp.sym.so"
    ant.move(file: workingDir + "/src/main/jniLibs/" + abi + "/libil2cpp.dbg.so", tofile: workingDir + "/symbols/" + abi + "/libil2cpp.so")
}

However, I also see that the pipeline cannot find a directory /src/main/Il2CppOutputProject/IL2CPP/build/deploy/il2cpp and it's true - the directory does not exist in unityLibrary.

I wonder what I can do to create the directory that is not found, or at least stop the task from looking for the file, or look for /libil2cpp.so. <- I want to achieve at least one of the milestones of the issue.

I build the project with the following versions:

  • Android Studio Arctic Fox: 2020.3.1
  • Unity version: 2021.3.14f1
  • Gradle version: 7.4

Pre-error messages printed in Azure DevOps:

  • Same issue here. Did you solve? Commented Jun 28, 2023 at 10:23
  • Hi, I've bypassed it but did not manage to solve the issue so it would be no help. I kept the question as I hope someone is able to provide the answer for those who still look for a solution. Commented Jun 28, 2023 at 10:45

    Finally I got rid of the error by making a "Clean Project" and "Rebuild Project" and the file libil2cpp.dbg.so gets generated again. I suppose some cache issues. Commented Jun 30, 2023 at 6:43
