Gradle报错：根项目无installRelease任务+调试签名文件找不到

Hey there! Let's work through these two Gradle problems step by step:

The installRelease task belongs to your app module, not the root project—that's why you're hitting the "task not found" error when running it directly from the root. Here's how to fix it:

• If using the command line, run the task with the module prefix to target the app module specifically:

  ./gradlew app:installRelease
  

• If using Android Studio, open the Gradle panel (usually on the right sidebar), navigate to app > Tasks > install > installRelease, then right-click and select "Run" to execute it from the correct module context.

Even though you've placed the file in the app directory, there are a few common culprits for this error:

1. Filename or path mismatch
   Double-check these details:

   • The filename is exactly capstoneproject.jks (note: filenames are case-sensitive on macOS/Linux—make sure you didn't accidentally use CapstoneProject.jks or another variation)
   • The file is directly in the app/ folder, not nested inside app/src/main or another subdirectory.

2. Gradle cache interference
   Old cached references can sometimes cause this issue. Try cleaning the cache and re-syncing:

   • Run this command in your terminal:

     ./gradlew clean
     

   • In Android Studio, click File > Sync Project with Gradle Files to refresh the configuration.

3. Explicit path verification
   To rule out relative path ambiguity, you can temporarily use an absolute path to test if the file is detected. Update your signingConfigs block like this (replace the path with your actual file location):

   signingConfigs {
       debug {
           keyAlias 'alias'
           keyPassword 'larissa'
           // Use absolute path for testing
           storeFile file('/Users/yourname/AndroidStudioProjects/YourProject/app/capstoneproject.jks')
           storePassword 'larissa81'
       }
   }
   

   If this works, switch back to the relative path and confirm the file is in the correct app/ directory.

4. File permissions (macOS/Linux)
   On Unix-based systems, ensure the JKS file has read permissions. Run this command in the app directory:

   chmod +r capstoneproject.jks
   

Here's your original app module build.gradle for reference:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 27
    signingConfigs {
        debug {
            keyAlias 'alias'

            storeFile file('capstoneproject.jks')
            storePassword 'larissa81'
        }
    }
