方法一：全局指定 settings.xml(第20行)

<!-- 指定本地仓库位置 -->
<localRepository>D:
epository</localRepository>

<!-- 指定远程镜像 -->
<mirrors>
  <mirror>
    <id>central</id>
    <mirrorOf>central</mirrorOf>
    <name>aliyunmaven</name>
    <url>https://maven.aliyun.com/repository/central</url>
  </mirror>
  <mirror>
    <id>apache.snapshots.https</id>
    <mirrorOf>apache.snapshots.https</mirrorOf>
    <name>aliyunmaven</name>
    <url>https://maven.aliyun.com/repository/apache-snapshots</url>
  </mirror>
</mirrors>

<!--指定JDK等参数-->
<profiles>
  <profile>
    <id>jdk-1.8</id>
    <activation>
      <jdk>1.8</jdk>
      <activeByDefault>true</activeByDefault>
    </activation>
    <properties>
      <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
      <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
      <maven.compiler.encoding>UTF-8</maven.compiler.encoding>
      <maven.compiler.source>1.8</maven.compiler.source>
      <maven.compiler.target>1.8</maven.compiler.target>
      <maven.compiler.compilerVersion>1.8</maven.compiler.compilerVersion>
    </properties>
  </profile>
</profiles>

方法二：当前项目 pom.xml中指定(第28行)

<properties>
    <java.version>11</java.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
</properties>

<repositories>
    <repository>
        <id>public</id>
        <url>https://maven.aliyun.com/repository/public</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </repository>
</repositories>

<pluginRepositories>
    <pluginRepository>
        <id>public</id>
        <url>https://maven.aliyun.com/repository/public</url>
        <snapshots>
            <enabled>false</enabled>
        </snapshots>
    </pluginRepository>
</pluginRepositories>

<build>
    <plugins>

            <configuration>

                <source>${java.version}</source>
                <target>${java.version}</target>
                <encoding>${project.build.sourceEncoding}</encoding>
            </configuration>
        </plugin>
        <!-- 跳过测试 -->
        <plugin>
