如何使用 IntelliJ IDEA 导出 JAR（JavaFX 和 Maven）

Question

我为 Maven 创建了一个带有 pom.xml 的新 JavaFX 项目。现在我想将它导出到一个可运行的 JAR 中。目前，我正在使用 IntelliJ IDEA 2017.1.1-2

如何做到这一点？

这是我现在的 pom.xml:

<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">

</build>
</project>

如何为此导出 JAR？

Answer 1

假设您修改 pom.xml 中的 <build> 标签，如下所示。

<build>
        <plugins>
            <plugin>
                <groupId>com.zenjava</groupId>
                <artifactId>javafx-maven-plugin</artifactId>
                <version>8.8.3</version>
                <configuration>
                    <mainClass>gui.Main</mainClass>
                </configuration>
            </plugin>
             <plugin>
          <artifactId>maven-assembly-plugin</artifactId>
          <configuration>
            <archive>
              <manifest>
                <mainClass>org.drawpvp.MainClass</mainClass>
              </manifest>
            </archive>
            <descriptorRefs>
              <descriptorRef>jar-with-dependencies</descriptorRef>
            </descriptorRefs>
          </configuration>
        </plugin>
        </plugins>
    </build>

Answer 2

免责声明：我是那个 javafx-maven-plugin 的维护者。

要执行 javafx-maven-plugin，您有两个选择：

将其作为正常 Maven 生命周期的一部分进行调用 mvn package
直接从插件的 cli/IDE 目标 jar 调用它

在使用选项 1（maven 生命周期）时使用此选项：

<plugin>
    <groupId>com.zenjava</groupId>
    <artifactId>javafx-maven-plugin</artifactId>
    <version>8.8.3</version>
    <configuration>
        <mainClass>gui.Main</mainClass>
    </configuration>
    <executions>
        <execution>
            <id>create-jfxjar</id>
            <phase>package</phase>
            <goals>
                <goal>build-jar</goal>
            </goals>
        </execution>
    </executions>
</plugin>

您的可执行 jar 文件将在 target/jfx/app/ 文件夹中生成。

您可以在 github 项目中查找一些示例：https://github.com/javafx-maven-plugin/javafx-maven-plugin/tree/master/src/it
