如何为exec-maven-plugin传递Java 17所需VM参数？

你的配置存在两处核心错误，导致JVM无法正确识别--add-opens参数：

• <commandlineArgs>被错误嵌套在<arguments>内部，两者属于互斥的参数配置方式
• --add-opens作为JVM参数，未按正确格式拆分为独立参数项传递

修正后的完整配置 #

删除原配置中的<commandlineArgs>标签，在<mainClass>之前添加独立的<argument>项传递JVM参数，修改后的配置如下：

                </configuration>
            </plugin>
        </plugins>
    </build>
</profile>

关键注意事项 #

• JVM参数位置：所有JVM参数必须放在<mainClass>标签之前，否则会被当作程序运行参数而非JVM参数处理
• 参数拆分规则：包含空格的参数（如--add-opens java.base/java.lang=ALL-UNNAMED）必须拆分为两个独立的<argument>标签，否则JVM无法正确解析
• 配置方式互斥：<commandlineArgs>和<arguments>不能混用，前者适合直接编写完整命令行字符串，后者适合结构化拆分参数
