我想构建具有EJB模块和WEB模块的Maven项目，而在WEB模块中需要EJB.

I want to build maven project having EJB module and WEB module, where EJB is needed in WEB module.

父pom.xml

<modelVersion>4.0.0</modelVersion> <groupId>cz.literak.oauth</groupId> <artifactId>OAuthLogin</artifactId> <packaging>pom</packaging> <version>1.0-SNAPSHOT</version> <modules> <module>OAuthLogin-web</module> <module>OAuthLogin-ejb</module> </modules> <name>OAuthLogin JEE Skeleton</name> <url>www.literak.cz/OAuthLogin/</url>

EJB pom.xml

<parent> <artifactId>OAuthLogin</artifactId> <groupId>cz.literak.oauth</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>OAuthLoginEJB</artifactId> <version>1.0-SNAPSHOT</version> <packaging>ejb</packaging> <name>OAuthLoginEJB Beans</name>

WEB pom.xml

<parent> <artifactId>OAuthLogin</artifactId> <groupId>cz.literak.oauth</groupId> <version>1.0-SNAPSHOT</version> </parent> <modelVersion>4.0.0</modelVersion> <artifactId>OAuthLoginWEB</artifactId> <packaging>war</packaging> <name>OAuthLogin Webapp</name> <dependencies> <dependency> <groupId>cz.literak.oauth</groupId> <artifactId>OAuthLogin-ejb</artifactId> <version>1.0-SNAPSHOT</version> <type>jar</type> <scope>compile</scope> </dependency> </dependencies>

Intellij Idea告诉我该版本未知.当我在父模块中运行 mvn clean install 时，它失败并显示:

Intellij Idea tells me that version is unknown. When I run mvn clean install in parent module, it fails with:

[ERROR] Failed to execute goal on project OAuthLoginWEB: Could not resolve dependencies for project cz.literak.oauth:OAuthLoginWEB:war:1.0-SNAPSHOT: Could not find artifact cz.literak.oauth:OAuthLogin-ejb:jar:1.0-SNAPSHOT -> [Help 1]

问题出在哪里?我没有运气就浏览了类似的问题.谢谢.

Where is the issue? I browsed similar questions without luck. Thanks.

推荐答案

您已经定义了ejb模块的artifactId，如下所示:

You have defined the artifactId of your ejb module like this:

<artifactId>OAuthLoginEJB</artifactId>

但不是

<artifactId>OAuthLogin-ejb</artifactId>

但您的依赖程度是这样的:

BUT YOUR DEPENDENCY is like this:

<dependencies> <dependency> <groupId>cz.literak.oauth</groupId> <artifactId>OAuthLogin-ejb</artifactId> <version>1.0-SNAPSHOT</version> <type>ejb</type> </dependency> </dependencies>
