Maven:从属性文件中设置pom.xml中的属性 [英] Maven: set property in pom.xml from properties file

问题描述

我有一个多模块项目，在不同模块版本上有很多依赖性.目前，版本已进行硬编码，因此需要手动进行更改.因此，我决定将所有这些文件放入属性文件，并在项目构建期间从中获取属性值.

I have multi-module project with a lot of dependencies on different modules versions. At the moment versions are hardcoded and one needs to change them manually. So I decided to put all of them to a properties file and get properties values from it during project build.

这是我尝试执行的操作:

Here is how I try to do it:

root pom.xml

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>properties-maven-plugin</artifactId>
    <version>1.0-alpha-2</version>
    <executions>
        <execution>
            <phase>initialize</phase>
            <goals>
                <goal>read-project-properties</goal>
            </goals>
            <configuration>
                <files>
                    <file>./version.properties</file>
                </files>
            </configuration>
        </execution>
    </executions>
</plugin>

文件version.properties

module1.version=1.1
module2.version=1.8
module3.version=5.4

pom.xml模块的示例

<properties>
    <module1.project.version>${module1.version}</module1.project.version>
</properties>

<parent>
    <groupId>com.mymodule</groupId>
    <artifactId>test</artifactId>
    <version>${module1.version}</version>
    <relativePath>../pom.xml</relativePath>
</parent>

构建失败，原因:

如何从文件中读取一些属性并以正确的方式配置pom.xml?

How can I read some properties from a file and configure pom.xml in correct way?

推荐答案

最后似乎很简单.我使用了initialize阶段.将其更改为validate可解决问题:

It appeared to be very simple at the end. I used initialize phase. Changing it to validate fixed the problem:

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>properties-maven-plugin</artifactId>
    <version>1.0-alpha-2</version>
    <executions>
        <execution>
            <phase>validate</phase>
