Error with mockito-core in cloud manager

[shelly-goel]

Hello,

We have upgrade all the junit versions in pom.xml and it worked absolutely fine in local server but when deployed in cloud manager with latest (2023.1) version, the build fails with below error:

15:31:46,075 [main] [ERROR] COMPILATION ERROR :

If we change the "mockito-core" version to 3.12.4, it builds fine.

Hi Shelly,

I assume on your local you got  Java 11 and pipeline fails with Java 1.8.

Create file .cloudmanager/java-version with 11 as content. [1] complete docs on subject.

This error indicates that code executed on Java 1.8, requires Java 11.

As per mockito-core release notes it's minimum requirements are Java 11.

So we need to point to cloudmanager pipeline you want Java 11 by creating relevant config.

Still getting the same issue. Is there a way to check cloud manager Java version?

Hi Shelly,

You can include exec plugin to tell you the java version during the build, it will be located in the build logs.

<plugin>
          <groupId>org.codehaus.mojo</groupId>
          <artifactId>exec-maven-plugin</artifactId>
          <version>1.3.2</version>
          <executions>
                <execution>
                  <id>java version printer</id>
                  
                  <phase>initialize</phase>

                  <goals>
                    <goal>exec</goal>
                  </goals>

                  <configuration>
                    <executable>mvn</executable>
                    <arguments>
                      <argument>-v</argument>
                    </arguments>
                  </configuration>

                </execution>
           </executions>
        </plugin> 

 Have googled around and found this blog post too:

The version being used in your local server is version 5.0.0, which has a class file version of 55.0, but the version being used in the cloud manager is an older version with a class file version of 52.0.

To resolve this issue, you'll need to ensure that the same version of the mockito-core library is being used in both your local server and the cloud manager. 

You would need to find the version which has class version of 52.0 and then use that in the pom file.
