maven-ear-plugin无法解析依赖关系

我试图使用maven插件创建一个ear文件,但它在耳朵项目pom上失败了。我已经盯着这几个小时了,无法解决这个问题。我使用eclipse所以我的所有项目,包括父项都在同一个目录中。

我的父pom.xml:

我的模块pom.xmls如下所示

<parent>
    <groupId>com.traintrack</groupId>
    <artifactId>traintrack-parent</artifactId>
    <relativePath>../traintrack-parent/pom.xml</relativePath>
    <version>${traintrack-version}</version>
</parent>
<groupId>com.traintrack</groupId>
<artifactId>traintrack-core</artifactId>
<version>${traintrack-version}</version>
<packaging>jar</packaging>

我收到以下错误

Failed to execute goal org.apache.maven.plugins:maven-ear-plugin:2.10:generate-application-xml (default-generate-application-xml) on project traintrack-ear: Artifact[jar:com.tracktrack:traintrack-core] is not a dependency of the project.

我一直在玩依赖项,我发现当我删除ear pom.xml中的依赖项部分时,我得到了同样的错误。它始终是耳朵中列出的第一个抛出错误的模块,而且所有模块都会这样做。

在某个地方可能是一个愚蠢的错误,但我无法发现它。任何帮助表示赞赏。

1 个答案:

答案 0 :(得分:3)

maven-ear-plugin的配置出错。 groupId的{​​{1}}应为traintrack-core,而不是com.traintrack

所以,改为:

com.tracktrack

使用此:

<jarModule>
    <groupId>com.tracktrack</groupId>
    <artifactId>traintrack-core</artifactId>
    <bundleDir>lib</bundleDir>
    <includeInApplicationXml>true</includeInApplicationXml>
</jarModule>

修改

<jarModule> <groupId>com.traintrack</groupId> <artifactId>traintrack-core</artifactId> <bundleDir>lib</bundleDir> <includeInApplicationXml>true</includeInApplicationXml> </jarModule> traintrack-web也应该这样做。


一些与问题无关的提示:

  • traintrack-services-authenticationdefault包装,无需声明
  • jardefault范围,无需声明

与问题无关的一些提示直接

  • 使用模块时,不必在子模块中声明compile。您可以从子模块中删除groupId(例如groupId)并继续运行=)
  • 当您使用maven模块并且traintrack-core与所有模块/项目相同时,您可以使用${project.groupId}来避免像您这样的错误,以及依赖关系groupId是相同的项目

E.g:

groupId
