Could not get unknown property 'classesDir' for main classes

Anuradha677 · August 20, 2019, 9:20am

I have run gradle build --stacktrace . I have replaced the version with latest version of gradle-appengine-plugin.
Here is my 2 build.gradle file of app engine.

apply plugin: ‘war’
apply plugin: ‘appengine’

war {
version = ‘1.0’
expand appengineProjectName: appengineProject
}

appengine {
version = ‘1’
project = appengineProject
downloadSdk = true
}

dependencies {
compile ‘javax.servlet:servlet-api:2.5’
compile ‘jstl:jstl:1.2’
compile ‘com.googlecode.objectify:objectify:6.0.4’
compile ‘com.google.endpoints:endpoints-framework:2.2.1’
appengineSdk ‘com.google.appengine:appengine-java-sdk:1.9.76’
}

another build.gradle

buildscript {
repositories {
mavenCentral()
}

dependencies {
    classpath 'com.google.appengine:gradle-appengine-plugin:1.9.59'
}

}

subprojects {
repositories {
mavenCentral()
}

apply plugin: 'java'
sourceCompatibility = '1.8'
targetCompatibility = '1.8'
tasks.withType(JavaCompile) { options.encoding = 'UTF-8' }

dependencies {
}

}

Exception is:
org.gradle.api.GradleScriptException: A problem occurred evaluating project ‘:endpoints-frontend’.

I suggest you raise an issue and perhaps even provide a pull request to the AppEnginePlugin.

Or you could use gradle 4.x instead of 5.x

Thanks Lance. I have already raised a concern on this.

Lance · August 21, 2019, 5:37am

It seems you linked your issue to another issue but you didn’t read the resolution.

The plugin has moved from here to here and is now at version 2.1.0.

You should be able to fix your issue by changing to

buildscript {
  repositories {
    mavenCentral()
  }

  dependencies {
    classpath 'com.google.cloud.tools:appengine-gradle-plugin:2.1.0'
  }
}
