maven构建失败。

maven项目编译报“Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.1”

　　

解决方案：setting.xml的节点<profiles>添加以下配置

<profile>
    <id>jdk18</id>
    <activation>
        <activeByDefault>true</activeByDefault>
        <jdk>1.8</jdk>
    </activation>
    <properties>
        <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>
