Idea使用Maven打包jar

创建好JavaFX项目后

在pom.xml文件中，添加项目入口类

<build>
    <plugins>
        <plugin>
            <groupId>org.apache.maven.plugins</groupId>
            <artifactId>maven-shade-plugin</artifactId>
            <version>1.2.1</version>
            <executions>
                <execution>
                    <phase>package</phase>
                    <goals>
                        <goal>shade</goal>
                    </goals>
                    <configuration>
                        <transformers>
                            <transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                                <mainClass>com.lee.MainApp</mainClass>
                            </transformer>
                        </transformers>
                    </configuration>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

其中 com.lee.MainApp 是入口类包含所在包的完整名称

打开Maven Projects视图
Views -> Tool Windows -> Maven Projects

选择 package ,运行 Run Maven Build(绿色三角)，或者直接双击pakcage

等待编译完成...

在目录 D:\workspace\java_idea\JavaFXDemo2\target 中可以看到编译后的jar文件 com.lee-1.0-SNAPSHOT.jar

运行jar文件

java -jar com.lee-1.0-SNAPSHOT.jar

注意:
在 windows 中 com.lee-1.0-SNAPSHOT 可能不合法，重命名后可以运行

rename com.lee-1.0-SNAPSHOT JavaFXDemo.jar
