无法在STS中构建基本SpringBoot应用程序

Question

我正在尝试在STS中创建一个默认的Spring Boot应用程序。它在STS文件中创建了一个“Spring starter Project”-->。创建项目后未进行任何更改。错误立即显示在POM文件中...

<groupId>com.example</groupId>
<artifactId>first-boot</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>jar</packaging>

<name>first-boot</name>
<description>Hello Spring Boot in STS</description>

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.0.5.RELEASE</version>
    <relativePath/> <!-- lookup parent from repository -->
</parent>

<properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
    <java.version>1.8</java.version>
</properties>

        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
</dependencies>

<build>
    <plugins>
        <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
        </plugin>
    </plugins>
</build>

按Alt+F5并从列表中选择您的项目，然后选中复选框“强制更新快照/发布”并单击“确定”。

现在右键单击project并选择run as->maven Build。
