After some research and trials on how to get the Maven project version in a SpringBoot application I couldn't find anything working for me.

Using a manifest is definitively a rotten path due to class loaders issues, i.e. one gets the first manifest Spring finds, which in my case was not the one of my application.

One solution I have found is to use the maven resources plugin to "filter" (replace) properties in resource files. In this case the Spring <code>application.properties</code>.

Below are the steps to make this work.

In the pom file, activate resources filtering with the following definition:

<pre><code>&lt;resources&gt;
 &lt;resource&gt;
 &lt;filtering&gt;true&lt;/filtering&gt;
 &lt;directory&gt;src/main/resources&lt;/directory&gt;
 &lt;includes&gt;
 &lt;include&gt;application.properties&lt;/include&gt;
 &lt;/includes&gt;
 &lt;/resource&gt;
&lt;/resources&gt;
</code></pre>

In the <code>application.properties</code> file:

<pre><code>application.name=@project.artifactId@
build.version=@project.version@
build.timestamp=@timestamp@
</code></pre>

Notice the @property@ instead of ${property}. in the <code>application.properties</code> file.

The <code>spring-boot-starter-parent</code> pom redefines the standard <code>${}</code> delimiter as <code>@</code>:

<pre><code>&lt;resource.delimiter&gt;@&lt;/resource.delimiter&gt;
&lt;!-- delimiter that doesn't clash with Spring ${} placeholders --&gt;
&lt;delimiters&gt;
 &lt;delimiter&gt;${resource.delimiter}&lt;/delimiter&gt;
&lt;/delimiters&gt;
</code></pre>

One can then access those properties in Spring using <code>@Value</code> like this:

<pre><code>@Value("${application.name}")
private String applicationName;

@Value("${build.version}")
private String buildVersion;

@Value("${build.timestamp}")
private String buildTimestamp;
</code></pre>

blocks|key|1521381|text|这可能是因为您的主pom没有声明spring启动父程序作为其父pom。因为在这种情况下，过滤是默认的，而不需要显式声明筛选。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1521382|对我来说，从：|1521383|<parent>

It's probably because your main pom doesn't declare spring-boot-starter-parent as its parent pom.
Because when so, the filtering is done by default, without needing to declare the filtering explicitly

For me changing from :

<pre><code>&lt;parent&gt;
 &lt;groupId&gt;com.mycompany&lt;/groupId&gt;
 &lt;artifactId&gt;mycompany-parent&lt;/artifactId&gt;
 &lt;version&gt;20&lt;/version&gt;
&lt;/parent&gt;
</code></pre>

to : 

<pre><code>&lt;parent&gt;
 &lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
 &lt;artifactId&gt;spring-boot-starter-parent&lt;/artifactId&gt;
 &lt;version&gt;1.5.6.RELEASE&lt;/version&gt;
&lt;/parent&gt;
</code></pre>

In my application main pom.xml fixed the issue without having to declare the filtering.

To get access to Maven properties in Spring Boot application all we need is map them with delimiter <code>@</code> in the <code>application.properties</code> like this:

<pre><code>app.version=@project.version@
app.name=@project.name@
</code></pre>

Then use them in the app like ordinary properties, for example:

<pre><code>@Service
public class SomeService {

 @Value("${app.version}")
 private String appVersion;

 // other stuff
}
</code></pre>

Source: <a href="https://docs.spring.io/spring-boot/docs/current/reference/html/howto-properties-and-configuration.html#howto-automatic-expansion-maven" rel="noreferrer">Automatic Property Expansion Using Maven</a>

But if you are using yaml to store application properties, you may need to replace delimiter <code>@</code> with some other one, for example <code>^</code> in our <code>pom.xml</code>:

<pre><code>&lt;plugin&gt;
 &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt;
 &lt;artifactId&gt;maven-resources-plugin&lt;/artifactId&gt;
 &lt;version&gt;2.7&lt;/version&gt;
 &lt;configuration&gt;
 &lt;delimiters&gt;
 &lt;delimiter&gt;^&lt;/delimiter&gt;
 &lt;/delimiters&gt;
 &lt;useDefaultDelimiters&gt;false&lt;/useDefaultDelimiters&gt;
 &lt;/configuration&gt;
&lt;/plugin&gt;
</code></pre>

Or even simpler - just replace variable <code>resource.delimiter</code> in <code>propeties</code> block of your pom.xml:

<pre><code>&lt;properties&gt;
 &lt;java.version&gt;11&lt;/java.version&gt;
 &lt;resource.delimiter&gt;^&lt;/resource.delimiter&gt;
&lt;/properties&gt;
</code></pre>

Then use it in your property file, for example:

<pre><code>app:
 version: ^project.version^
 name: ^project.name^
</code></pre>

There a easier way to do this, don't need to add application.properties or delimiter changes.
Simply add plugin with goal build-info and Autowire start up class with bean BuildProperties.
<pre><code>&lt;plugin&gt;
&lt;groupId&gt;org.springframework.boot&lt;/groupId&gt;
 &lt;artifactId&gt;spring-boot-maven-plugin&lt;/artifactId&gt;
 &lt;version&gt;2.1.3.RELEASE&lt;/version&gt;
 &lt;executions&gt;
 &lt;execution&gt;
 &lt;goals&gt;
 &lt;goal&gt;build-info&lt;/goal&gt;
 &lt;/goals&gt;
 &lt;/execution&gt;
 &lt;/executions&gt;
&lt;/plugin&gt;
</code></pre>
Startup class will have
<pre><code>@Autowired
 BuildProperties buildProperties;
</code></pre>
later in <code>@PostConstruct</code> in start up class you can call multiple methods to retrieve build Timestamp, Version, Name of Artifact, Group etc.
<pre class="lang-java prettyprint-override"><code>
private static final Logger LOGGER = LoggerFactory.getLogger(YourSpringApplication.class);

@Autowired
BuildProperties buildProperties;

public static void main(String[] args) {
 SpringApplication.run(YourSpringApplication.class, args);
 }

@PostConstruct
 private void logVersion() {
 LOGGER.info(buildProperties.getName());
 LOGGER.info(buildProperties.getVersion());
 LOGGER.info(buildProperties.get(&quot;time&quot;));
 LOGGER.info(buildProperties.getGroup());
}
</code></pre>
The <code>info</code> actuator will automatically use, and display this information if it detects it, as well as display <a href="https://docs.spring.io/spring-boot/docs/1.5.10.RELEASE/reference/htmlsingle/#production-ready-application-info-git" rel="noreferrer">git information</a> if it finds any.
