本文介绍了使用Maven分发Akka微内核应用程序的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我有一个用Java开发的akka​​微内核应用程序. 为了分发该应用程序，我使用了JCrankyi博客

I have an akka micro kernel application developed in java. To distributed the application , I used the tutorials at the JCrankyi's blog

jcranky/2012/07/13/akka-microkernel-with-maven/#comment-1322

使用maven-assembly-plugin和akka启动脚本.

using the maven-assembly-plugin and the the akka start script.

descriptor.xml如下所示

the descriptor.xml is presented below

<id>akka</id> <formats> <format>zip</format> </formats> <fileSets> <fileSet> <directory>${Com-RubineEngine-GesturePoints}</directory> <outputDirectory>/deploy</outputDirectory> <includes> <include>*.jar</include> </includes> </fileSet> </fileSets> <dependencySets> <dependencySet> <outputDirectory>/lib</outputDirectory> </dependencySet> </dependencySets> <files> <file> <source>src/main/start</source> <outputDirectory>/bin</outputDirectory> </file> <file> <source>src/main/resources/application.conf</source> <outputDirectory>/config</outputDirectory> </file> </files> </assembly>

POM.xml中的片段

The snippets from the POM.xml

<plugin> <artifactId>maven-assembly-plugin</artifactId> <version>2.3</version> <configuration> <descriptors> <descriptor>/descriptor.xml</descriptor> </descriptors> </configuration> <executions> <execution> <id>make-assembly</id> <phase>package</phase> <goals> <goal>single</goal> </goals> </execution> </executions> </plugin>

起始文件是批处理文件，其内容如下所示.

the start file is a batch file and the content is presented below.

@echo off set SAMPLE=%~dp0.. set AKKA_HOME=%SAMPLE%\..\..\..\.. set JAVA_OPTS=-Xms1024M -Xmx1024M -Xss1M -XX:MaxPermSize=256M -XX:+UseParallelGC set AKKA_CLASSPATH=%AKKA_HOME%\lib\scala-library.jar;%AKKA_HOME%\lib\akka\* set SAMPLE_CLASSPATH=%SAMPLE%\config;%AKKA_CLASSPATH%;%SAMPLE%\lib\* java %JAVA_OPTS% -cp "%SAMPLE_CLASSPATH%" -Dakka.home="%SAMPLE%" akka.kernel.Main

以下是来自Maven Assembly:assembly插件的错误.

the error from the maven assembly:assembly plugin is presented below.

推荐答案

我认为错误非常明显.

C:\Users\FAISAL\Desktop\disaster\com-theta-gesture\src\main\start isn't a file

我假设src/main/start是一个文件夹，您将必须在该文件夹中指定文件名.至少它不被识别为文件.

I assume that src/main/start is a folder and you will have to specify the name of a file in that folder. At least it is not recognized as a file.

<files> <file> <source>src/main/start</source> <outputDirectory>/bin</outputDirectory> </file> </files>

我认为您应该按照src/main/scripts中. html"rel =" nofollow>标准目录布局简介.

I think you should put the start script in src/main/scripts as described in the Introduction to the Standard Directory Layout.

<files> <file> <source>src/main/scripts/start.bat</source> <outputDirectory>/bin</outputDirectory> </file> </files>

修改

为了验证您的start文件确实是文件，只需将简单的JUnit测试添加到您的src/main/test目录.这是一个简单的示例:

In order to verify that your start file is really a file then just add a simple JUnit test to your src/main/test directory. Here is a simple example:

package com.stackoverflow; import org.junit.Test; import java.io.File; import static org.junit.Assert.assertTrue; /** * @author maba, 2012-11-08 */ public class FileTest { @Test public void testIfStartScriptIsFile() { File file = new File("src/main/scripts/start.bat"); assertTrue("The tested file is not a real file!!!", file.isFile()); } }
