当我执行gradlew appengineRun时，我一直得到：

我有一台Windows 7主机。相同的程序与gradlew bootRun运行良好。 我没有使用web.xml。但我的build.gradle与https://cloud.google.com/appengine/docs/standard/java/tools/gradle一致。 我没有经历eclipse（类似的问题在这里报道：mvn appengine:run - error 403 (spring boot web with jsp)）。 springBootVersion =＆＃39; 2.0.0.BUILD-SNAPSHOT＆＃39;

的build.gradle：

buildscript {
    ext {
        springBootVersion = '2.0.0.BUILD-SNAPSHOT'
    }
    repositories {
        mavenCentral()
        maven { url "https://repo.spring.io/snapshot" }
        maven { url "https://repo.spring.io/milestone" }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
        classpath 'com.google.cloud.tools:appengine-gradle-plugin:+'    // latest App Engine Gradle tasks
    }
}

apply plugin: 'java'                              // standard Java tasks
apply plugin: 'war'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'
apply plugin: 'com.google.cloud.tools.appengine'  // App Engine tasks

ext['thymeleaf.version'] = '3.0.9.RELEASE'

compileJava {
    options.warnings = true
    options.debug = true
    options.compilerArgs += ["-Xlint:deprecation"]
}

sourceSets {
    main {
        java {
            exclude '**/RedirectHttpToHttpsOnTomcatConfig.java'
            exclude '**/RedirectHttpToHttpsOnJettyConfig.java'
            exclude '**/RedirectHttpToHttpsOnJetty2Config.java'
            exclude '**/RedirectHttpToHttpsOnJetty3Config.java'
            exclude '**/RedirectHttpToHttpsOnJetty4Config.java'
       }
   }
}

repositories {
    mavenCentral()
    maven { url "https://repo.spring.io/snapshot" }
    maven { url "https://repo.spring.io/milestone" }
}

dependencies {
    compile 'com.google.appengine:appengine-api-1.0-sdk:+'  // Latest App Engine Api's
    providedCompile 'javax.servlet:javax.servlet-api:3.1.0'
    compile 'jstl:jstl:1.2'

    compile('org.springframework.boot:spring-boot-starter-thymeleaf')
    compile("org.springframework.boot:spring-boot-starter-web") {
        exclude module: "spring-boot-starter-tomcat"
    }
    compile("org.springframework.boot:spring-boot-starter-jetty")
    compile('org.springframework.boot:spring-boot-starter-actuator')
    compile('org.springframework.boot:spring-boot-starter-security')
    compile('org.thymeleaf.extras:thymeleaf-extras-springsecurity4')
    compile("org.springframework.boot:spring-boot-starter-jdbc") {
        exclude module: "org.apache.tomcat:tomcat-juli"
    }
    compile("org.springframework.boot:spring-boot-starter-data-jpa") {
        exclude module: "org.apache.tomcat:tomcat-juli"
    }
    compile("com.h2database:h2")
    providedRuntime 'org.slf4j:jul-to-slf4j'
}

configurations {
    compile.exclude module: 'spring-boot-starter-tomcat'
    runtime.exclude module: 'spring-boot-starter-tomcat'
}

appengine {  // App Engine tasks configuration
  deploy {   // deploy configuration

  }
}

sourceCompatibility = 1.8     // App Engine Flexible uses Java 8
targetCompatibility = 1.8     // App Engine Flexible uses Java 8
