Question

我在尝试进行maven构建时遇到以下错误。

无法执行目标org.apache.maven.plugins：maven-compiler-plugin：3.7.0：在项目上编译（default-compile）

Maven版本是3.5.3。 maven编译器插件版本是3.7.0。因为它有什么问题吗？

我安装了jdk1.8。所以，这是在eclipse中使用的默认版本 pom.xml中指定的插件如下（自动生成）。

<plugins>
      <plugin>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.7.0</version>
        <configuration>
          <source>1.8</source>
          <target>1.8</target>
        </configuration>
      </plugin>
      <plugin>
        <artifactId>maven-war-plugin</artifactId>
        <version>3.0.0</version>
        <configuration>
          <warSourceDirectory>WebContent</warSourceDirectory>
        </configuration>
      </plugin>
    </plugins>

我的是一个春天的mvc项目。我认为，我的代码和代码配置是正确的。 maven有问题。我删除了.me / repository。但没有改变。 IDE使用的是Eclipse Oxygen。
