尝试使用Alakai插件将Launch4j集成到Maven项目中

1. 没有配置.xml，您需要在pom.xml文件中配置launch4j。
2. 你可以使用maven-assembly-plugin，但我建议你使用maven-shade-plugin。
3. 不需要指定launch4j安装，此插件可以100%工作。
4. 确定。遵循我使用的shade和launch4j配置，它使用不同的主类生成两个exe，一个控制台和一个GUI：

                </jre>
            </configuration>
        </execution>
    </executions>
</plugin>

或者，您可以在 launch4j-plugin 上省略 “jar” 标记并删除 shade-plugin 的额外配置，但请注意，这将用 shaded jar（具有嵌入式依赖项）替换流的主 jar（没有嵌入依赖项），并且这个 jar 将安装在本地存储库上，或者在需要时在反应器中使用。
