如何解决Maven依赖关系的问题＆＃34;无法在项目上执行目标＆＃34;

Question

我在maven项目的 Eclipse 中有以下结构：

MainMavenProject
---MyProject
---MProject-client
---MProject-xyz
---MProject-web
...

在Eclipse中，我使用 JBoss 7.1 来运行MProject-web：

现在，我想用另一个项目运行Jetty。从目录 / MainMavenProject / MyProject 我运行一个命令

mvn -Djetty:port=8081 jetty:run

已完成错误：

[ERROR] Failed to execute goal on project MyProject: Could not resolve dependencies for project ***.*****.MyProject:MyProject:war:0.0.1-SNAPSHOT: The following artifacts could not be resolved: ***.*****.********:MyProject-client:jar:1.0.

在MyProject中，我使用依赖于其他的：

<dependency>
    <groupId>com.*****.********</groupId>
    <artifactId>MyProject-client/artifactId>
    <version>1.0.1-SNAPSHOT</version>
</dependency>

<dependency>
    <groupId>com.*****.********</groupId>
    <artifactId>MProject-xyz</artifactId>
    <version>1.0.1-SNAPSHOT</version>
</dependency>

我如何检查，究竟发生了什么以及之后如何解决？

提前谢谢

首先尝试在主项目上运行mvn install。

您的项目缺少其他模块，这些模块可能从未安装到本地存储库。

并非每次都要在运行jetty:run之前运行安装。

另一种方法是使用eclipse，右键单击MyProject - ＆gt;以 - ＆gt;运行Maven build ...，在目标字段中输入-Djetty:port=8081 jetty:run并选中＆＃34; Resolve workspace artifacts＆＃34;。
