我正在尝试将 Gradle Vaadin 插件添加到我的项目中，但出现以下错误。

这是插件的页面：https ://github.com/johndevs/gradle-vaadin-plugin/wiki

而且，这是我的 build.gradle 文件：

buildscript {
    ext {
        springBootVersion = '1.5.3.RELEASE'
    }
    repositories {
        mavenCentral()

        maven {
      url "http://maven.vaadin.com/vaadin-addons"
    }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

plugins {  
    id 'com.devsoap.plugin.vaadin' version '1.2.1'
        id 'org.springframework.boot' version '1.5.3.RELEASE'
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'jacoco'
apply plugin: 'application'

jar {
    baseName = 'testapp'
    version = '0.0.1-SNAPSHOT'
}

sourceCompatibility = 1.8

repositories {
    mavenCentral()
        flatDir {
       dirs 'libs'
   }
    maven {
      url "http://maven.vaadin.com/vaadin-addons"
  }
}

sourceSets {
  main {
    output.resourcesDir = "build/classes/main"
  }

  uiTest {
      java.srcDirs=['src/ui-test/java','src/main/java']

}

// Create a new task called uiTest and set its type to Test.

configurations {
  uiTestCompile.extendsFrom testCompile
  uiTestRuntime.extendsFrom testRuntime
}
task uiTest(type: Test) {
  testClassesDir = sourceSets.uiTest.output.classesDir
  classpath = sourceSets.uiTest.runtimeClasspath
}

dependencyManagement {
    imports {
        mavenBom "com.vaadin:vaadin-bom:8.0.3"
    }
}

jacocoTestReport {
    reports {
        xml.enabled = true
        html.enabled = true
    }
}

check.dependsOn jacocoTestReport

springBoot {  
  // Main class of @SpringBootApplication
  mainClass = 'com.sample.test.Application'
}

当我检查 gradle 依赖项时，我看到了“javax.validation:validation-api”的 2 个版本。我相信这是导致问题的原因，但我找不到强制 vaadin-client 使用“javax.validation:validation-api:1.0.0.GA”的方法。

如果您能帮助我更正 build.gradle，我将不胜感激。

Gradle Vaadin 插件必须看到 Springboot 插件才能进行正确的设置。所以你必须先使用 Springboot 插件，然后再使用 Vaadin 插件。

您看到错误的原因是javax.validationSpringboot 的 1.1 的 dep 覆盖了所有配置（也是用于为 Vaadin 构建客户端的配置）

附带说明：您两次应用 Springboot 插件——一次 in plugins，一次使用apply. 我会摆脱buildscript-block 和apply. 然后交换里面的物品plugins。
