我有一个父项目pom看起来像这样：

该项目中的模块具有以下pom：

    <?xml version="1.0" encoding="UTF-8"?>
    <project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>cf-tenant-prov.common</artifactId>
    <dependencies>

        <dependency>

            <artifactId>javax.servlet-api</artifactId>
            <version>4.0.1</version>
        </dependency>


        <dependency>
            <groupId>iaik</groupId>
            <artifactId>iaik_jce</artifactId>
            <version>${iaik.iaik_jce.version}</version>

        <dependency>

            <version>${jackson.version}</version>
        </dependency>
      </dependencies>
    </project>

这可以在我的机器上成功构建，但是在jenkins构建中，如果有人克隆了这个git并进行了maven构建，我将收到如下错误：

[ERROR] [ERROR] Some problems were encountered while processing the POMs:

[ERROR] 'dependencies.dependency.version' for iaik:iaik_jce:jar must be a valid version but is '${iaik.iaik_jce.version}'. @ com.sap.it.cf:cf-tenant-prov.common:
[unknown-version], C:\Users\I501807\git\hcisvcprov\cf-tenant-prov.parent\cf-tenant-prov.common\pom.xml 
<file:///C:/Users/XXXXXX/git/hcisvcprov/cf-tenant-prov.parent/cf-tenant-prov.common/pom.xml> , line 33, column 22

所有版本。

当这些属性位于单独的小球中时，这是较早的工作。

我只是将这些依赖关系上移了一层，以使它们不会在每个pom文件中重复出现。

2 个答案:

答案 0 :(得分：0)

您的父母说它是3.3.0-SNAPSHOT版。但是您的模块引用的是版本3.2.0-SNAPSHOT。这些属性是否已经包含在3.2.0-SNAPSHOT中，或者您只是忘记增加模块POM中的版本？

答案 1 :(得分：0)

您的父pom.xml应该具有所有依赖项（每个依赖项 将在子模块中使用）

<dependencyManagement>
  .
  .
</dependencyManagement>

包括它们的版本（您可以使用属性或直接指定版本），然后可以在任何子模块中使用这些依赖项，甚至无需指定版本。

父pom.xml应该看起来像：-
