Spring Tool Suite org.joda 在 Gradle 项目中无法解析

Question

我已经使用 Spring Tool Suite 启动了一个 Gradle 项目。按照本教程：https : //spring.io/guides/gs/gradle/ 它表明我应该在我的 build.gradle 文件中添加 org.joda 依赖项，在类中导入依赖项，构建包，然后它应该可以使用。但是，当我这样做并重新构建项目并运行它时，出现错误：Exception in thread "main" java.lang.Error: Unresolved compilation problems:     LocalTime cannot be resolved to a type    LocalTime cannot be resolved to a type    at firstGradleProject.HelloWorld.main(HelloWorld.java:7)我的依赖项似乎已正确设置：dependencies {    compile('org.springframework.boot:spring-boot-starter')    testCompile('org.springframework.boot:spring-boot-starter-test')    compile('joda-time:joda-time:2.2')    testCompile('junit:junit:4.12')}如何在我的 Gradle Spring 项目中导入这个依赖项并让它编译？我的整个 build.gradle 文件看起来像：buildscript {    ext {        springBootVersion = '2.0.4.RELEASE'    }    repositories {        mavenCentral()    }    dependencies {        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")    }}apply plugin: 'java'apply plugin: 'eclipse'apply plugin: 'org.springframework.boot'apply plugin: 'io.spring.dependency-management'group = 'com.example'version = '0.0.1-SNAPSHOT'sourceCompatibility = 1.8targetCompatibility = 1.8jar {    baseName = 'gs-gradle'    version =  '0.1.0'}repositories {    mavenCentral()}dependencies {    compile('org.springframework.boot:spring-boot-starter')    testCompile('org.springframework.boot:spring-boot-starter-test')    compile('joda-time:joda-time:2.2')    testCompile('junit:junit:4.12')}
