为了跟进pauxu的回答，我在我的一个项目中使用了launch4j和NSIS，并认为展示我的使用方式会有所帮助。这是我为Windows做的事情。顺便说一句，我正在为Mac创建.app和.dmg，但是还没有弄清楚Linux怎么做。
launch4j和NSIS的项目副本
在我的项目中，我有一个“供应商”目录，在它的下面有一个“ launch4j”和“
nsis”目录。每个文件中都有每个应用程序的安装副本。我发现在项目本地拥有一个副本比强迫其他人安装两个产品并设置某种指向每个产品的环境变量要容易得多。
脚本文件
我的项目中还有一个“脚本”目录，其中包含项目的各种配置/脚本文件。首先是launch4j.xml文件：
<launch4jConfig> <dontWrapJar>true</dontWrapJar> <headerType>gui</headerType> <jar>rpgam.jar</jar> <outfile>rpgam.exe</outfile> <errTitle></errTitle> <cmdLine></cmdLine> <chdir>.</chdir> <priority>normal</priority> <downloadUrl>http://www.rpgaudiomixer.com/</downloadUrl> <supportUrl></supportUrl> <customProcName>false</customProcName> <stayAlive>false</stayAlive> <manifest></manifest> <icon></icon> <jre> <path></path> <minVersion>1.5.0</minVersion> <maxVersion></maxVersion> <jdkPreference>preferJre</jdkPreference> </jre> <splash> <file>..imagessplash.bmp</file> <waitForWindow>true</waitForWindow> <timeout>60</timeout> <timeoutErr>true</timeoutErr> </splash></launch4jConfig>
然后是NSIS脚本rpgam-setup.nsis。可以使用VERSION参数来帮助命名文件。
; The name of the installerName "RPG Audio Mixer"!ifndef VERSION !define VERSION A.B.C!endif; The file to writeoutfile "..distinstallerswindowsrpgam-${VERSION}.exe"; The default installation directoryInstallDir "$PROGRAMFILESRPG Audio Mixer"; Registry key to check for directory (so if you install again, it will ; overwrite the old one automatically)InstallDirRegKey HKLM "SoftwareRPG_Audio_Mixer" "Install_Dir"# create a default section.section "RPG Audio Mixer" SectionIn RO ; Set output path to the installation directory.

我的Ant构建文件（build.xml）中有一些目标可以处理上述问题。首先，我打电话给Ant导入launch4j的Ant任务：
<property name="launch4j.dir" location="vendor/launch4j" /><taskdef name="launch4j" classname="net.sf.launch4j.ant.Launch4jTask" classpath="${launch4j.dir}/launch4j.jar:${launch4j.dir}/lib/xstream.jar" />然后，我有了一个用于创建包装可执行文件的简单目标：
<target name="executable-windows" depends="jar" description="Create Windows executable (EXE)"> <launch4j configFile="scripts/launch4j.xml" outfile="${exeFile}" /></target>制作安装程序的另一个目标：
<target name="installer-windows" depends="executable-windows" description="Create the installer for Windows (EXE)"> <!-- Lay out files needed for building the installer --> <mkdir dir="${windowsLayoutDirectory}" /> <copy file="${jarFile}" todir="${windowsLayoutDirectory}" /> <copy todir="${windowsLayoutDirectory}/lib"> <fileset dir="${libraryDirectory}" /> <fileset dir="${windowsLibraryDirectory}" /> </copy> <copy todir="${windowsLayoutDirectory}/icons"> <fileset dir="${iconsDirectory}" /> </copy> <copy todir="${windowsLayoutDirectory}" file="${exeFile}" /> <mkdir dir="${windowsInstallerDirectory}" /> <!-- Build the installer using NSIS --> <exec executable="vendor/nsis/makensis.exe"> <arg value="/DVERSION=${version}" /> <arg value="scripts/rpgam-setup.nsi" /> </exec></target>上面的部分只是将安装程序所需的文件复制到一个临时位置，而下半部分执行使用所有脚本制作安装程序的脚本。
