Error: Could not find or load main class after adding dependency (maven)

Question

In Java project I use Maven as a project manager. To my project's pom.xml file I add the following dependency:

<dependency>
        <groupId>org.neo4j</groupId>
        <artifactId>neo4j</artifactId>
        <version>2.1.0-M01</version>
</dependency>

When I try to run the project I get an error:

Could not find or load main class 'package.className'

I'm using Eclipse 4.2 Keppler with m2e plugin.

Answer 1

在Debian（可能也是其他Linux）上，您应该删除〜/〜/ .m2 / repository文件夹，然后在Eclipse中右键单击项目Maven-> Update Project...。

Answer 2

在Eclipse工作台模式下，选择项目，然后单击Alt + F5来更新该项目的Maven依赖项。请告诉我它是否解决了问题
