Jar Package packaged as exe example

The jar package is packaged as an EXE sample description

For a MAVEN-based Java project, it is usually packaged as a jar,
If you want to package the jar file as an EXE file, you only need to add a plugin to the Pom.xml configuration file.

Here we use launch4j

Environment

• jdk1.8
• Maven 3.5.2

Main method

The logic is simple, that is, if the command line has parameters, print the first parameter of the command line,
No parameters print "Hell world!".

package com.hui;/** * Hello world! */publicclass App {    publicstaticvoidmain(String[] args) {        if (null != args && args.length0) {            System.out.println(args[0]);        else {            System.out.println("Hello World!");        }    }}

Pom.xml Example

Just add the following plugins to the build link

<build>        <plugins>            <plugin>                <groupId>Com.akathist.maven.plugins.launch4j</groupId>                <artifactId>Launch4j-maven-plugin</artifactId>                <executions>                    <execution>                        <id>L4j-clui</id>                        <phase>Package</phase>                        <goals><goal>Launch4j</goal></goals>                        <configuration>                            Console                            <outfile>Target/encc.exe</outfile>                            <jar>Target/java2exe-1.0-snapshot.jar</jar>                            <errTitle>Encc</errTitle>                            <classPath>                                <mainClass>Com.hui.App</mainClass>                                <addDependencies>False</addDependencies>                                <preCp>Anything</preCp>                            </classPath>                            <jre>                                <minVersion>1.5.0</minVersion>                            </jre>                            <versionInfo>                                <fileVersion>1.2.3.4</fileVersion>                                <txtFileVersion>TXT file version?</txtFileVersion>                                <fileDescription>A description</fileDescription>                                <copyright>My copyright</copyright>                                <productVersion>4.3.2.1</productVersion>                                <txtProductVersion>TXT product version</txtProductVersion>                                <productName>E-n-c-c</productName>                                <internalName>Ccne</internalName>                                <originalFilename>Original.exe</originalFilename>                            </versionInfo>                        </configuration>                    </execution>                </executions>            </plugin>            <plugin>                <artifactId>Maven-assembly-plugin</artifactId>                <executions>                    <execution>                        <id>Assembly</id>                        <phase>Package</phase>                        <goals><goal>Single</goal></goals>                        <configuration>                            <descriptors>                                <descriptor>Assembly.xml</descriptor>                            </descriptors>                        </configuration>                    </execution>                </executions>            </plugin>        </plugins>    </build>

Create a new Assembly.xml file in the project root directory at the same time

<assemblyxmlns="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>Cdc-upgrade</id>    <formats>        <format>Zip</format>    </formats>    <includeBaseDirectory>False</includeBaseDirectory>    <fileSets>        <fileSet>            <directory>${project.build.directory}</directory>            <outputDirectory>/</outputDirectory>            <includes>                <include>*.exe</include>            </includes>        </fileSet>    </fileSets></assembly>
