To check the Spring Cloud version being used during application startup

1. Check the Logs

Spring Cloud typically logs the release train version during application startup. Look for a log entry similar to this:

2025-01-16 16:49:23.914 INFO [main] - Spring Cloud X.Y.Z (Release Train: <Name>)

In this log:

• X.Y.Z is the Spring Cloud version.
• <Name> refers to the Spring Cloud release train (e.g., "Hoxton", "Greenwich").

2. Enable Debug Logs

To get more details, enable debug logs when starting the application by adding the following argument to your run command:

--debug

This provides a detailed conditions report, including information about the Spring Cloud version.

3. Check pom.xml or build.gradle

Examine the dependency in your build configuration to determine the Spring Cloud version.

Maven (pom.xml)

Search for spring-cloud-dependencies:

<dependencyManagement> <dependencies> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-dependencies</artifactId> <version>...</version> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement>

The <version> tag contains the Spring Cloud release train.

Gradle (build.gradle)

Search for springCloudVersion or dependency declarations:

ext { springCloudVersion = '...' } dependencies { implementation platform("org.springframework.cloud:spring-cloud-dependencies:${springCloudVersion}") }

---

4. Use the Spring Boot Actuator

If you have the Spring Boot Actuator dependency, you can retrieve version details through the /actuator/info endpoint:

1. Add the info endpoint in your application.properties or application.yml:

   management.endpoint.info.enabled=true management.endpoints.web.exposure.include=info

2. Start the application and access:

   http://localhost:8080/actuator/info

   This may include the Spring Cloud version.

---

5. Use dependency:tree (Maven) or dependencies (Gradle)

Maven:

Run

mvn dependency:tree | grep spring-cloud

This will list all Spring Cloud dependencies and their versions.

Gradle:

Run:

./gradlew dependencies | grep spring-cloud

This will show the dependency versions.

---

6. Check the META-INF Directory

Inspect the META-INF directory of the packaged JAR file:

1. Extract the JAR file:

   jar -xf your-app.jar

2. Check the META-INF/MANIFEST.MF or META-INF/spring-boot.properties file for version information.
