从属性文件读取pom依赖版本

时间:2020-07-13 07:16:01

标签: java maven pom.xml

试图从属性文件中读取版本,但低于异常

  1. 生命周期配置未涵盖插件执行:org.codehaus.mojo:properties-maven-plugin:1.0-alpha-2:read-project-properties (执行:默认,阶段:初始化)
  2. 缺少工件org.springframework.cloud:spring-cloud-starter-zipkin:jar:$ {zipkin-version}

下面是pom.xmlproperties文件

version.properties file
zipkin-version=2.2.2.RELEASE

2 个答案:

答案 0 :(得分:3)

依赖关系在执行插件之前已解决。

因此您在<dependencies>部分中看不到使用properties-maven-plugin读取的属性。

如果要通过属性设置依赖项版本,则必须在POM内部,命令行或settings.xml中设置此属性。

答案 1 :(得分:-1)

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,如果找不到该文件,您应该得到一条正确的错误消息。

另一个建议:spring-cloud-starter-zipkin属于org.springframework.cloud组,该组遵循另一个版本。声明依赖关系的建议方法如下:

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