在 NetBeans 中生成可执行 jar [英] Producing executable jar in NetBeans

问题描述

我使用的是 NetBeans 6.5，出于某种原因，它不会开箱即用"生成可执行的 jar.

I'm using NetBeans 6.5 and for some reason it won't produce executable jar "out of the box".

我将我的项目设置为主项目，在项目属性运行"菜单中定义了主类，当我按 F6 运行它时，它完美无缺.

I set my project to be the main project, defined main class in the project properties "run" menu and it works flawlessly when I press F6 to run it.

我查看了清单文件，它确实没有在那里定义主类，也省略了库依赖项.

I looked at the manifest file and it indeed didn't define the main class there, and also omitted the library dependencies.

我错过了什么吗?有没有办法(除了手动更改清单文件)来生成可执行的 jar 文件?

是的，我尝试过清理和重建，它在 dist 文件夹中生成了 jar，仍然具有相同的 manifest.mf

yes, I tried clean and rebuild and it produced the jar in the dist folder, still with the same manifest.mf

Manifest-Version: 1.0
Ant-Version: Apache Ant 1.7.1
Created-By: 10.0-b23 (Sun Microsystems Inc.)

推荐答案

我刚刚在 NetBeans 7.2.1 的 Maven Java 应用程序项目中遇到了同样的问题.修改 pom.xml 文件以包含 Maven 程序集插件，对 myrho 的答案进行了一次调整(需要引用预定义的描述符jar-with-dependencies"):

I just had the same problem in NetBeans 7.2.1 with a Maven Java Application project. Modify the pom.xml file to include the maven assembly plugin with one tweak to myrho's answer (needs to reference the predefined descriptor "jar-with-dependencies"):

<plugin>
    <artifactId>maven-assembly-plugin</artifactId>
    <version>2.4</version>
    <configuration>
        <descriptorRefs>
            <descriptorRef>jar-with-dependencies</descriptorRef>
        </descriptorRefs>
        <archive>
            <manifest>
                <mainClass>your.app.MainClass</mainClass>
            </manifest>
        </archive>
    </configuration>
    <executions>
        <execution>
            <id>make-assembly</id>
            <phase>package</phase>
            <goals>
                <goal>single</goal>
            </goals>
        </execution>
    </executions>
</plugin>

另一种方法是在不使用 Maven 的 NetBeans 中构建 Java 应用程序项目.选择 File -> Project Properties -> Build -> Packaging 并选中Copy Dependent Libraries"复选框.

An alternate method is to build a Java Application project in NetBeans that doesn't use Maven. Select File -> Project Properties -> Build -> Packaging and check the "Copy Dependent Libraries" checkbox.
