[英]Create a executable java maven project
我已經使用Maven創建了一個項目。 主要思想是輕松獲得依賴關系。 問題是,現在我無法創建可執行文件.exe甚至.jar文件。 我的應用程序是Java原型,並且正在使用Netbeans進行處理。 另外,我正在使用Postgree數據庫。 我的pom文件顯示如下:
<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">

<artifactId>mtuapp</artifactId>
<version>0.1-alpha</version>

我實際上想為我的應用程序創建一個安裝程序。

我嘗試按照建議使用maven-jar-plugin
創建和可執行jar文件。 我的新pom文件是:
<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">

有了這個我得到:

我可以看到您的項目是使用maven創建的,因此您的jar文件是在項目的root
目錄下的目標文件夾中創建的,您只需要執行目標mvn clean package
即可生成它,但這不會成為可執行jar文件。
如果要創建安裝程序並創建.exe文件,則需要使用其他工具。我建議您使用http://www.jrsoftware.org/isdl.php,您可以在此處找到文檔。
----編輯----
如果要創建可執行jar,則必須在pom文件中添加以下幾行插件:
<build>
<plugins>
<plugin>
<!-- Build an executable JAR -->
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
<mainClass>com.mypackage.MyClass</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
</plugins>
</build>
在此處查看完整信息
如果要包括Maven依賴項,則可以使用maven-assembly-plugin
<plugin>
<artifactId>maven-assembly-plugin</artifactId>
<configuration>
<archive>
<manifest>
<mainClass>fully.qualified.MainClass</mainClass>
</manifest>
</archive>
<descriptorRefs>
<descriptorRef>jar-with-dependencies</descriptorRef>
</descriptorRefs>
</configuration>
</plugin>
