从属性文件中读取 pom 依赖版本

Question

正在尝试从属性文件中读取版本但低于异常

Plugin execution not covered by lifecycle configuration: org.codehaus.mojo:properties-maven-plugin:1.0-alpha-2:read-project-properties (execution: default, phase: initialize)

Missing artifact org.springframework.cloud:spring-cloud-starter-zipkin:jar:${zipkin-version}

下面是 pom.xml 和 properties 文件

version.properties file
zipkin-version=2.2.2.RELEASE

Answer 1

在执行插件之前解决依赖关系。

因此您使用 properties-maven-plugin 读取的属性在 <dependencies> 部分不可用。

如果你想通过属性设置一个依赖版本，这个属性必须在POM里面设置，在命令行或者在settings.xml.

Answer 2

您正在使用旧版本的插件 (1.0-alpha-2)，请将其更新为 latest 1.0.0。

然后确保文件 version.properties 在文件夹 C:\Workspace 中。无论如何，使用最新版本的插件，如果找不到文件，您应该会收到正确的错误消息。

再提一个建议：spring-cloud-starter-zipkin属于org.springframework.cloud组，跟在另一个版本之后。声明该依赖项的建议方法如下所示：

<properties>
    <java.version>1.8</java.version>
    <spring-cloud.version>Hoxton.SR6</spring-cloud.version>
</properties>

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>${spring-cloud.version}</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

<dependencies>
    <!-- ... -->
    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-zipkin</artifactId>
    </dependency>
    <!-- ... -->
</dependencies>
