Gradle 使用Spring boot部署AppEngine Flexible+；格雷德尔，码头错误

我有一个使用gradle和spring boot的GoogleAppEngine应用程序。我的build.gradle文件如下所示：

buildscript {
repositories {
    mavenCentral()
}
dependencies {
    classpath("org.springframework.boot:spring-boot-gradle-plugin:1.3.5.RELEASE")
    classpath 'io.spring.gradle:dependency-management-plugin:0.6.1.RELEASE'

    classpath 'com.google.cloud.tools:appengine-gradle-plugin:+'    // latest App Engine Gradle tasks       
    }
}
    apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'
apply plugin: 'war'
apply plugin: 'com.google.cloud.tools.appengine'  // App Engine tasks
war {
    baseName = 'gs-accessing-mongodb-data-rest'
    version =  '0.1.0'
}
repositories {
    mavenCentral()
}
configurations {
    providedRuntime
}
sourceCompatibility = 1.8
targetCompatibility = 1.8
dependencies {
    providedCompile group: 'javax.servlet', name: 'servlet-api', version:'2.5'
    compile 'com.google.appengine:appengine:+'
    compile("org.springframework.boot:spring-boot-starter-data-rest")

    compile 'org.mongodb:mongo-java-driver:3.2.2'    
}
appengine {  // App Engine tasks configuration
  deploy {   // deploy configuration
    stopPreviousVersion = true  // default - stop the current version
    promote = true              // default - & make this the current version
  }
}
group = 'com.acin.shelfcheck'   // Generated output GroupId
version = '1.0-SNAPSHOT'          // Version in generated output
eclipse {
    project.natures 'org.eclipse.buildship.core.gradleprojectnature'
}

当我尝试在Google AppEngine Flexible中部署我的应用程序时，出现以下错误：
