需求描述

有时候我们写了一个可执行的java程序，利用maven很轻松地打成了可执行的jar包。

然是只能在安装了jdk的平台上才可以直接双击运行。那我不像利用第三方工具，可以直接打成windows可执行的exe包吗？

可以的

一款融合了launch4j的maven插件，可以帮我们实现这个难题

直接上代码 pom.xml

                </executions>
            </plugin>
        </plugins>
    </build>
</project>

注意修改我留的备注，再贴一下assembly.xml放在根目录

<assembly xmlns="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/plugins/maven-assembly-plugin/assembly/1.1.2 http://maven.apache.org/xsd/assembly-1.1.2.xsd">
    <id>取个名字</id>
    <formats>
        <format>zip</format>
    </formats>
    <includeBaseDirectory>false</includeBaseDirectory>
    <fileSets>
        <fileSet>
            <directory>out/artifacts/</directory>
            <outputDirectory>out/artifacts/</outputDirectory>
            <includes>
                <include>*.exe</include>
            </includes>
        </fileSet>
    </fileSets>
</assembly>

好了，这样运行maven命令build就会在你设置好的路径下打出exe包了！
