使用jar文件運行Java程序（Netbeans/Maven） - 需要幫助

我的目標是構建我的程序並能夠從cmd行執行。當我清理構建的應用程序，我得到以下錯誤，當我運行它：使用jar文件運行Java程序（Netbeans/Maven） - 需要幫助

我不是一個Java開發者，但我理解，這是因爲pom.xml中配置的（當然希望我理解;））

這裏是我的POM的配置：

我現在應該做的是能夠執行從CMD行的jar文件？

編輯：我已經嘗試過：

sses/* com.google.api.services.samples.dfareporting.cmdline.DfaReportingSample

THX對您有所幫助。

「由於：java.lang.ClassNotFoundException：com.google.api.client.json.JsonFact ory」Clealy指出，您從類路徑中遺漏了這個。 – dosdebug

我編譯後，我得到了我的目標目錄如下：的CheckStyle-求CacheFile 的CheckStyle-checker.xml 的CheckStyle-header.txt 的CheckStyle，爲result.xml 類爲dfareporting-CMDLINE樣本-1.0.0.jar findbugsXml.xml generated-sources maven-archiver surefire 因此，基於此，運行它的命令應該是什麼？ – Rgonomike

你看到是否有你的jar打包的libs？或者，如果你從你的pom.xml引用它們到正確的路徑？因爲我不認爲如果你的庫被打包到jar中。 – dosdebug

添加到您的pom.xml文件：

<build> 
<plugins> 
<plugin> 
<groupId>org.apache.maven.plugins</groupId> 
<artifactId>maven-dependency-plugin</artifactId> 
<executions> 
<execution> 
<id>copy-dependencies</id> 
<phase>prepare-package</phase> 
<goals> 
<goal>copy-dependencies</goal> 
</goals> 
<configuration> 
<outputDirectory>${project.build.directory}/dependency-jars</outputDirectory> 
<overWriteReleases>false</overWriteReleases> 
<overWriteSnapshots>false</overWriteSnapshots> 
<overWriteIfNewer>true</overWriteIfNewer> 
</configuration> 
</execution> 
</executions> 
</plugin> 
<plugin> 
<groupId>org.apache.maven.plugins</groupId> 
<artifactId>maven-jar-plugin</artifactId> 
<configuration> 
<archive> 
<manifest> 
<addClasspath>true</addClasspath> 
<mainClass>FULLPACKAGENAME.CLASSNAME</mainClass> 
<classpathPrefix>dependency-jars/</classpathPrefix> 
</manifest> 
<manifestEntries> 
<Class-Path>.</Class-Path> <!-- HERE IS THE IMPORTANT BIT --> 
</manifestEntries> 
</archive> 
</configuration> 
</plugin> 
</plugins> 
</build>

然後先用乾淨的行家，然後建立作爲Maven的。

您需要將所有庫添加到類路徑中。

例如，如果您所有的依賴都在工作目錄lib文件夾，那麼你的命令應該是：

java -cp dfareporting-cmdline-sample-1.0.0.jar;./lib/* com.google.api.services.samples.dfareporting.cmdline.DfaReportingSample

UPD。

還有其他解決方案。

你應該這個插件添加到您的pom.xml：

<plugin> 
    <groupId>org.apache.maven.plugins</groupId> 
    <artifactId>maven-assembly-plugin</artifactId> 
    <executions> 
    <execution> 
     <goals> 
     <goal>attached</goal> 
     </goals> 
     <phase>package</phase> 
     <configuration> 
     <descriptorRefs> 
      <descriptorRef>jar-with-dependencies</descriptorRef> 
     </descriptorRefs> 
     <archive> 
      <manifest> 
      <mainClass>Your.Main.class</mainClass> 
      </manifest> 
      <manifestEntries> 
      <Premain-Class>Your.agent.class</Premain-Class> 
      <Agent-Class>Your.agent.class</Agent-Class> 
      <Can-Redefine-Classes>true</Can-Redefine-Classes> 
      <Can-Retransform-Classes>true</Can-Retransform-Classes> 
      </manifestEntries> 
     </archive> 
     </configuration> 
    </execution> 
    </executions> 
</plugin>

然後就是從這個插件運行的彙編的目標，你會得到所有你的代碼和庫在一個罐子。

您也可以通過命令行做到這一點：

> mvn org.apache.maven.plugins:maven-assembly-plugin:2.2-beta-2:assembly

不應該它如果它是一個Maven項目，會不一樣？在我的代碼中，我有這些導入語句，並且代碼與Netbeans 'import com.google.api.client.json.JsonFactory; import com.google.api.client.json.jackson2.JacksonFactory;' – Rgonomike

@Rgonomike，nope，你應該將所有庫添加到你的類路徑中......但是，還有另一種解決方案。這需要對你的pom.xml進行一些修改。查看我的更新。 – pbespechnyi

謝謝，Mr.777給了我一個解決方案。沒有下載依賴關係。現在他們是但他們不在罐子裏，這對我來說很好。我暫時不會進一步挖掘。謝謝！ – Rgonomike
