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

问题描述

我正在使用NetBeans 6.5，由于某种原因，它不会生成开箱即用的可执行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要项目，在项目属性运行菜单中定义主类，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，它确实没有那里定义主类，也省略了库依赖。

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？有没有办法（除了手动更改清单文件）生成可执行的jar文件？

Am I missing something? Is there a way (other than manually altering the manifest file) to produce executable jar files?

编辑：是的，我尝试清理并重建它在dist中产生了jar文件夹，仍然使用相同的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

我在NetBeans 7.2.1中遇到了与Maven Java Application项目相同的问题。修改pom.xml文件以包含 maven程序集插件，一个调整到myrho的答案（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NetBeans中构建一个不使用Maven的Java Application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.
