Update gradle version for google app engine

Question

I'm trying to run my java application on Google Cloud App Engine, I'm getting following error: org.gradle.api.GradleException: Spring Boot plugin requires Gradle 4.0 or later. The current version is Gradle 2.12 org.gradle.api.GradleException: Spring Boot plugin requires Gradle 4.0 or later. The current version is Gradle 2.12

I tried to update the gradle-wrapper.properties to use gradle 4.5.1 and uploaded my own gradle-wrapper.jar

gradle-wrapper.properties

#Tue Apr 17 09:15:25 SGT 2018
distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-4.5.1-all.zip

I try to run the gradle init --type java-library to update the version and also tried gradle appengineBuild and gradle appengineDeploy but all of them give the same error message with the --stacktrace tag.

I also tried to restart the project but when i run the gradle init --type java-library command to startup a new project, it installs the 2.12 version

Does anyone have any idea what to do to fix this ?

Edit

I used following tutorials: Using Gradle and Gradle

With both tutorials i get the same end result, which is the error. I tried using following command to change the gradle version:

gradle wrapper --gradle-version 4.7 init --type java-application

Here the Error is : Execution failed for task ':init'. > The requested build setup type 'java-application' is not supported. Execution failed for task ':init'. > The requested build setup type 'java-application' is not supported. . When the project is already set up it gives the original error when running this command.

So i tried using --type basic but this also gives me the original error.

When trying gradlew following error comes up:

    marketing@online-marketing-buddy:~/OnlineMarketingBuddyDB_AppEngine$ ./gradlew.bat 
-bash: ./gradlew.bat: Permission denied

I have no clue what to do next.

Answer 1

I had the same problem and I have followed the next steps to fix it:

1. Follow Gradle in AE standard environment guide until "Testing your application with the development server" step 3 (excluded).
2. In Google Cloud Shell, go to /opt/ folder and execute rm -rf gradle to uninstall Gradle version 2.12. Remove gradle , gradle.w and .gradle in your application folder. You might have something different here.
3. Download the compatible version you want from here .
4. Unzip the new Gradle version in two places: /opt/ and your application folder. You will need sudo permissions in /opt/ folder to perform any operation. Eg: sudo unzip gradle-4.5.1-bin.zip
5. Change the Gradle installation folder name in both places to gradle . Eg: sudo mv gradle-4.5.1 gradle .
6. Run gradle appengineRun in your application folder.
