java - Maven 不解析父 pom.xml 文件中的属性

Question

我有一个父项目 pom 如下所示:

    <?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" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            </dependency>
        </dependencies>
    </dependencyManagement>
</project>

该项目中的模块具有如下所示的 poms:

    <?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"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <groupId>com.sss.it.cf</groupId>

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

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

        </dependency>
        <dependency>
            <groupId>javax.servlet</groupId>
            <artifactId>javax.servlet-api</artifactId>

        </dependency>


        <dependency>
            <groupId>iaik</groupId>
            <artifactId>iaik_jce</artifactId>
            <version>${iaik.iaik_jce.version}</version>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-core</artifactId>
            <version>${jackson.version}</version>
        </dependency>
      </dependencies>
    </project>

这在我的机器上成功构建，但在 jenkins 构建中，如果有人克隆这个 git 并执行 Maven 构建，我会收到如下错误:

[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 

适用于所有版本。

当这些属性位于单独的 pom 中时，这在早期是有效的。

我只是将这些依赖项上移了一级，这样它们就不会在每个 pom 文件中重复。

Answer 1

您的家长说它是版本 3.3.0-SNAPSHOT。但您的模块引用的是版本 3.2.0-SNAPSHOT。这些属性是否已包含在 3.2.0-SNAPSHOT 中，还是您只是忘记在模块 POM 中增加版本？
