我是 Netbeans 和 Java 应用程序开发新手。我只需要知道如何使用 Netbeans 创建可执行 jar。我的应用程序包含 GUI 并采用了一些依赖库。
以下是我的 pom.xml:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>
<groupId>com.oli</groupId>
<artifactId>FFmpegchunker</artifactId>
<version>1.0.0</version>
<packaging>jar</packaging>
<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>com.oli.ffmpegchunker.MainScreen</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
</plugins>
</build>
<dependencies>
<dependency>

<dependency>

<version>1.7.5</version>
</dependency>
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-simple</artifactId>
<version>1.6.4</version>
</dependency>
</dependencies>
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<maven.compiler.target>1.8</maven.compiler.target>
</properties>
</project>
在目标文件夹中创建了一个 jar,但它不可执行。
最佳答案
您需要将依赖项打包到可执行 jar 中。 这是一个 2 步过程: 首先,将所有必需的依赖项复制到一个文件夹中:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>prepare-package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
<configuration>
<outputDirectory>
${project.build.directory}/libs
</outputDirectory>
</configuration>
</execution>
</executions>
</plugin>
现在所有依赖项都将复制到 libs 文件夹中。
第二步是创建可执行文件和类路径感知 jar,其中包含第一步中复制的依赖项的链接:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>libs/</classpathPrefix>
<mainClass>
com.oli.ffmpegchunker.MainScreen
</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
整体 pom 看起来像:
<?xml version="1.0" encoding="UTF-8"?>

您可以在 here 上找到一些更简单的可执行 jar 创建方法。使用maven assembly插件和shade插件。
关于java - 在netbeans中使用maven java应用程序制作可执行jar,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/59531029/
