引言:因为我记得在几年前回答了这个问题后，我经常提到这个问题，展示了一个动态访问Maven POM信息的动态版本(例如，也在测试期间)，今天我发现了一个类似的问题，涉及从另一个模块B访问模块a的Maven信息。

I thought about it for a moment and spontaneously had the idea to use a special annotation, applying it to a package declaration in package-info.java. I also created a multi-module example project on GitHub. I do not want to repeat the whole answer, so please see solution B in this answer. The Maven setup involves Templating Maven Plugin, but could also be solved in a more verbose way using a combination of resource filtering and adding generated sources directory to the build via Build Helper Maven. I wanted to avoid that, so I simply used Templating Maven.

第一步:如果你使用Spring Boot，你的pom.xml应该已经包含了Spring - Boot -maven-plugin。您只需要添加以下配置。

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <executions>
        <execution>
            <id>build-info</id>
            <goals>
                <goal>build-info</goal>
            </goals>
        </execution>
    </executions>
</plugin>

它指示插件执行build-info目标，默认情况下不会运行。这会生成关于应用程序的构建元数据，包括工件版本、构建时间等。

步骤2:使用buildProperties bean访问构建属性。在我们的例子中，我们创建了一个restResource来访问我们的webapp中的构建信息

@RestController
@RequestMapping("/api")
public class BuildInfoResource {
    @Autowired
    private BuildProperties buildProperties;

    
    @GetMapping("/build-info")
    public ResponseEntity<Map<String, Object>> getBuildInfo() {
        Map<String, String> buildInfo = new HashMap();
        buildInfo.put("appName", buildProperties.getName());
        buildInfo.put("appArtifactId", buildProperties.getArtifact());
        buildInfo.put("appVersion", buildProperties.getVersion());
        buildInfo.put("appBuildDateTime", buildProperties.getTime());
        return ResponseEntity.ok().body(buldInfo);
    }
}

我希望这能有所帮助

假设你正在使用Java，你可以:

Create a .properties file in (most commonly) your src/main/resources directory (but in step 4 you could tell it to look elsewhere). Set the value of some property in your .properties file using the standard Maven property for project version: foo.bar=${project.version} In your Java code, load the value from the properties file as a resource from the classpath (google for copious examples of how to do this, but here's an example for starters). In Maven, enable resource filtering. This will cause Maven to copy that file into your output classes and translate the resource during that copy, interpreting the property. You can find some info here but you mostly just do this in your pom: <build> <resources> <resource> <directory>src/main/resources</directory> <filtering>true</filtering> </resource> </resources> </build>

你还可以获取其他标准属性，如project.name, project.description，甚至是你放在pom <properties>中的任意属性，等等。资源过滤与Maven概要文件相结合，可以在构建时为您提供可变的构建行为。当您在运行时使用-PmyProfile指定配置文件时，可以启用属性，然后可以在构建中显示这些属性。

使用这个库可以获得简单的解决方案。向清单中添加您需要的任何内容，然后按字符串查询。

 System.out.println("JAR was created by " + Manifests.read("Created-By"));

http://manifests.jcabi.com/index.html

打包的工件包含META-INF/maven/${groupId}/${artifactId}/pom。属性文件，内容如下:

#Generated by Maven
#Sun Feb 21 23:38:24 GMT 2010
version=2.5
groupId=commons-lang
artifactId=commons-lang

许多应用程序使用这个文件在运行时读取应用程序/jar版本，不需要任何设置。

上述方法的唯一问题是，该文件(目前)是在包阶段生成的，因此在测试期间不会出现(有一个Jira问题可以改变这一点，请参阅MJAR-76)。如果这对您来说是一个问题，那么Alex描述的方法就是正确的方法。
