带有财产的Maven版本 [英] Maven version with a property

问题描述

我有大型Maven（第谷）项目，大约有400个插件。

I have big Maven (Tycho) project witch about 400 plug-ins.

我们在每个POM文件中指定了应用程序版本。

We have specified version of application in each POM file.

有没有办法如何指定所有POM的版本：仅限于一个地方？

Is there a way how to specify the version for all POM:s only on one place?

我希望有人会这样想：

I would expect some think like:

<properties>
<buildVersion>1.1.2-SNAPSHOT</buildVersion>
</properties>

....

<version>${buildVersion}</version>

我们有父 pom.xml ：

<modelVersion>4.0.0</modelVersion>
<groupId>company</groupId>
<artifactId>build.parent</artifactId>
<version>1.1.2-SNAPSHOT</version>
<packaging>pom</packaging>

然后在每个POM中引用父POM：

Then in each POM is reference to parent POM:

<parent>
  <artifactId>build.parent</artifactId>
  <groupId>company</groupId>
  <relativePath>../build.parent/pom.xml</relativePath>
  <version>1.1.2-SNAPSHOT</version>
</parent>

<modelVersion>4.0.0</modelVersion>
<groupId>company</groupId>
<artifactId>artifact</artifactId>
<version>1.1.2-SNAPSHOT</version>
<packaging>eclipse-plugin</packaging>

推荐答案

如果您有父项目，可以设置版本在父pom和子节点中，您可以使用 $ {project.version} 或 $ {version} 属性引用兄弟库。

If you have a parent project you can set the version in the parent pom and in the children you can reference sibling libs with the ${project.version} or ${version} properties.

如果你想避免在每个孩子中重复父母的版本：你可以这样做：

If you want to avoid to repeat the version of the parent in each children: you can do this:

<modelVersion>4.0.0</modelVersion>
<groupId>company</groupId>
<artifactId>build.parent</artifactId>
<version>${my.version}</version>
<packaging>pom</packaging>

<properties>
<my.version>1.1.2-SNAPSHOT</my.version>
</properties>

然后在你孩子的pom中你必须这样做：

And then in your children pom you have to do:

    <parent>
      <artifactId>build.parent</artifactId>
      <groupId>company</groupId>
      <relativePath>../build.parent/pom.xml</relativePath>
      <version>${my.version}</version>
    </parent>

    <modelVersion>4.0.0</modelVersion>
    <groupId>company</groupId>
    <artifactId>artifact</artifactId>
    <packaging>eclipse-plugin</packaging>

    <dependencies>
        <dependency> 
           <groupId>company</groupId>
           <artifactId>otherartifact</artifactId>   
           <version>${my.version}</version>
or
           <version>${project.version}</version>
        </dependency>
    </dependencies>
