Latest gradle plugin release fails with ExplodeWarTask.preserve() error

[Richard Perfect]

Hi,

This is my first day learning Google App-Engine, but I got stuck for a while on what looks to be a problem with the latest release of the Gradle plugin.

In the build.gradle example here; It seems the 1.3.3 release (from a few days ago on Sep 19th) gives me the following error;

C:\Projects\App-Engine-Gradle-Hello>gradlew compileJava

FAILURE: Build failed with an exception.

* Where:

Build file 'C:\Projects\App-Engine-Gradle-Hello\build.gradle' line: 23

* What went wrong:

A problem occurred evaluating root project 'App-Engine-Gradle-Hello'.

> com.google.cloud.tools.gradle.appengine.standard.ExplodeWarTask.preserve(Lorg/gradle/api/Action;)Lorg/gradle/api/tasks/Sync;

* Try:

Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.

BUILD FAILED

But when I downgrade to one of the earlier releases e.g. 1.3.2 I don't get this issue.

It turns out that I was using an older version of Gradle and it seems that there's a difference between 1.3.2 and 1.3.3 that now requires a Gradle version of 3.+ instead of 2.x

Updating my gradle wrapper version to 3.3 solved the problem.

gradle wrapper --gradle-version 3.3

Just posting in case this helps someone, and so hopefully Google search finds this post for someone else.

Complete stacktrace follows for search engine indexing.

Thanks for posting. I also experienced this, although strangely on a project that was last built and ran successfully in May... coming back to it today, any task I run gives this NoSuchMethodError.

This unfortunately also includes invoking the gradle wrapper task, so I had to:

- Comment out all my appengine plugin stuff in my build.gradle

- Then generate the wrapper

Then invoking commands with ./gradlew instead of plain gradle worked.
