java - 将 1.8 Maven 项目更改为编译为 1.16 会产生“无效的目标版本 1.16”

问题描述

我一直在寻找解决方案几个小时，甚至找不到一篇关于 maven 编译到 1.16 的帖子

我最近决定将我的一个项目从 java 8 升级到 16，因此我安装了 16 个 JDK 并相应地更改了我的构建部分（在 pom.xml 中）：

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-compiler-plugin</artifactId>
            <version>3.8.1</version>
            <configuration>
                <source>1.16</source> //used to be 1.8
                <target>1.16</target> //used to be 1.8
                <compilerArgs>
                    <arg>-parameters</arg>
                </compilerArgs>
            </configuration>
        </plugin>
    </plugins>
</build>

但是当我尝试安装时出现以下错误：

解决方案

  1. It's not 1.16, it's 16.
  2. You don't have to configure the maven-compiler-plugin.
  3. You can use the new release option.
  <properties>
    <maven.compiler.release>16</maven.compiler.release>
  </properties>
