Guava: Guava Breaking in Kotlin Jar: java.lang.NoSuchMethodError

[AdamSHurwitz]

Issue

The Java/Kotlin application runs as expected in from the Main Class in IntelliJ's IDE. However, when the app is built into a .Jar file the following error occurs: java.lang.NoSuchMethodError: com.google.common.util.concurrent.MoreExecutors. I've created the corresponding StackOverflow post.

Full Error Message

Gradle Dependency Tree

Attempted Solutions

1. After examining similar issues on StackOverflow this appears to be related to a conflict with Google's Guava library. From the Gradle Dependencies above some libraries were calling older versions of Guava. All libraries in the build.gradle have been updated to their latest versions.
2. Rebuilding project.
3. IntelliJ Invalidate Cache and Restart
4. Implementing current version of Guava in build.gradle: implementation 'com.google.guava:guava:26.0-android'
5. Implementing lowest version of Guava in build.gradle found in dependency tree: implementation 'com.google.guava:guava:19.0'
6. Implementing highest version of Guava in build.gradle found in dependency tree: implementation 'com.google.guava:guava:20.0'
7. Attempting to exclude lowest version of Guava in build.gradle found in dependency tree: configurations {all*.exclude 'com.google.guava:guava:19.0'}

See here for the solution regarding using Kotlin's Ktor library to manage AppEngine apps.

This is a known issue with Google Cloud Java libraries, which I know we're working on solving for people. However, it's not an issue with Guava _per se_, so I'm closing this issue.

@netdpb Any update on this issue as it still occurring?: https://stackoverflow.com/questions/53566910/kotlin-jar-error-exception-in-thread-timer-0-java-lang-nosuchmethoderror?noredirect=1#comment94035381_53566910

Thank you!

I've added a comment on the stackoverflow issue.

Solution

The Jar build started working again after updating my library dependencies and redefining the Project level SDK when re-pulling a version built on a different machine from Github.

Update to dependencies

1. Changed compile to implementation.
2. Updated version numbers by searching for each project's latest version on Google.

    ext.kotlin_version = '1.3.10'

    dependencies {
