however, if you haven't done any of this before you may need to do one other, one time only step.

Close eclipse, then run the following command from the shell:

I changed eclipse.ini file and added following and restarted eclipse

If Maven->Update Project doesn't work for you?
These are the steps I religiously follow.
Remove the project from eclipse (do not delete it from workspace)
Close Eclipse
go to command line and run these commands.

<pre><code>mvn eclipse:clean
mvn eclipse:eclipse -Dwtpversion=2.0
</code></pre>

Open Eclipse
import existing Maven project.
You will see the maven dependency in our project.

Hope this works.

If you use an eclipse plugin to do your maven tasks (there are 2 of them : M2ecipse from sonatype the 'official' one and q4e on Google Code) then, there are options in the contextual menus (right click on the project) to do that painlessly.

You can have both plugins running at the same time in your eclipse workbench and use them indifferently on a per project basis.

You could also consider to maven-dependency-plugin to your pom:

<pre><code>&lt;plugins&gt;
... 
 &lt;plugin&gt; 
 &lt;artifactId&gt;maven-dependency-plugin&lt;/artifactId&gt; 
 &lt;executions&gt; 
 &lt;execution&gt; 
 &lt;phase&gt;process-resources&lt;/phase&gt; 
 &lt;goals&gt; 
 &lt;goal&gt;copy-dependencies&lt;/goal&gt; 
 &lt;/goals&gt; 
 &lt;configuration&gt; 
 &lt;outputDirectory&gt;${project.build.directory}/lib&lt;/outputDirectory&gt; 
 &lt;/configuration&gt; 
 &lt;/execution&gt; 
 &lt;/executions&gt; 
 &lt;/plugin&gt; 
...
&lt;/plugins&gt;
</code></pre>

Than you can run "mvn package" and maven will copy all needed dependencies to your_project_path/target/your_project_name/WEB-INF/lib/ directory. From there you can copy them to your project/lib dir and add as external jars (configuring your project settings buildpath)

Likely quite simple but best way is to edit manually the file .classpath at the root of your project folder with something like
<pre><code>&lt;classpathentry kind=&quot;con&quot; path=&quot;org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER&quot;&gt;
 &lt;attributes&gt;
 &lt;attribute name=&quot;maven.pomderived&quot; value=&quot;true&quot;/&gt;
 &lt;attribute name=&quot;org.eclipse.jst.component.dependency&quot; value=&quot;/WEB-INF/lib&quot;/&gt;
 &lt;/attributes&gt;
 &lt;/classpathentry&gt;

I have created a <code>Maven</code> project and I want to add all <code>Maven</code> dependencies in build path of the project in <code>Eclipse</code>. When I go to Java Build Path > Add Library > Maven Managed Dependency > Next in property dialog of the project, it asks me to Use "Maven Project Setting" to configure Maven dependency resolution.

My question is how to add maven dependencies in current build path?

How to add "Maven Managed Dependencies" library in build path eclipse?

Eclipse

Java

我已经创建了一个Maven项目，我想在Eclipse中添加该项目的构建路径中的所有Maven依赖项。当我在项目的属性对话框中转到Java Build Path > Add Library > Maven Managed Dependency > Next时，它会要求我使用"Maven project Setting“来配置Maven依赖项解析。我的问题是如何在当前构建路径中添加maven依赖项？
