Build failed

I tried to build on and react-native expo project by going to android folder and by running ./gradlew assembleRelease. But it is giving error while building with these error messages:

Task :react-native-savanitdev-thermal-printer:bundleReleaseLocalLintAar FAILED

FAILURE: Build failed with an exception.

• What went wrong: Execution failed for task ':react-native-savanitdev-thermal-printer:bundleReleaseLocalLintAar'.

  Error while evaluating property 'hasLocalAarDeps' of task ':react-native-savanitdev-thermal-printer:bundleReleaseLocalLintAar'. Direct local .aar file dependencies are not supported when building an AAR. The resulting AAR would be broken because the classes and Android resources from any local .aar file dependencies would not be packaged in the resulting AAR. Previous versions of the Android Gradle Plugin produce broken AARs in this case too (despite not throwing this error). The following direct local .aar file dependencies of the :react-native-savanitdev-thermal-printer project caused this error: C:\Users\pronali\Desktop\Projects\PronaliERP\PronaliBilling\node_modules\react-native-savanitdev-thermal-printer\android\libs\printer-lib-3.1.6.aar

I solved it finally by editing and deleting some files in /node_modules/react-native-savanitdev-thermal-printer. Here are the steps by which I followed and resolve the build error:

1. Go to /node_modules/react-native-savanitdev-thermal-printer/android/libs/ folder and extract the printer-lib-3.1.6.aar file using WinRAR or any other archival software.
2. You will get a classes.jar file inside the printer-lib-3.1.6.aar file after extraction.
3. Rename classes.jar file to printer-lib-3.1.6.jar and keep it on /node_modules/react-native-savanitdev-thermal-printer/android/libs/ folder
4. Remove the printer-lib-3.1.6.aar file and extracted folder.
5. Edit /node_modules/react-native-savanitdev-thermal-printer/android/build.gradle file:

   dependencies {
   ....
   implementation fileTree(dir: "libs", include: ["*.jar"])   // remove the aar from the list
   ......
   implementation files('libs/zywell.jar')
   implementation files('libs/printer-lib-3.1.6.jar')   //rename the extension with jar
   }

6. Now build the apk and the error will be gone. Thanks!
