I am trying to learn microservices by creating a dummy project. I have a config repository in git and a config server running at port 8888.It's working properly as I can see my settings as below:
Now I have two microservice projects 1) customer service and 2) customer-account-service. customer microservice is running properly while customer-account-microservice is unable to start and throwing below exception:

Please help me in fixing the above exception.
                May I ask why the h2 dependency is part the the dependencyManagement block instead the dependencies block?

                @sn42 copy paste error and after moving h2 dependency under dependencies block, code worked. Thanks alot for pointing this error.

in my case, I had a space after the "driver"
spring.datasource.driverClassName=org.h2.Driver...
I deleted it and it works just fine
I change it to 'compile' and it solved my problem.
        <dependency>
            <groupId>com.h2database</groupId>
            <artifactId>h2</artifactId>
            <version>1.4.200</version>
            <scope>compile</scope>
        </dependency>
                Sad, but true, ItelliJ is becoming more and more an Eclipse-next-gen. Right mouse on the project->maven->reload project also seems to help

                I was using gradle and had the same issue with Intellij.  Restart solved the problem.  Thank you Ashish!

In my case the problem was caused by some trailing blank characters behind the driver classname in application.properties
This fails (dots in the code snippet below should be read as whitespace chars):
spring.datasource.driverClassName=org.h2.Driver...
This succeeds:
spring.datasource.driverClassName=org.h2.Driver
In my case I gave the gradle dependency wrong.
I should give it in dependencies {implementation}, but I gave it in dependencies {testImplementation} in build.gradle file
The below mentioned is right
dependencies {
  implementation 'com.h2database:h2:2.1.212' 
I had this problem because I was using an outdated version of the h2 dependency :
<dependency>
        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>
        <version>1.4.193</version>
    </dependency>
I fixed it by removing the version tag so that the latest version is downloaded :
<dependency>
        <groupId>com.h2database</groupId>
        <artifactId>h2</artifactId>
    </dependency>
In my case,
In application.properties file, there are white spaces after adding configurations
You can see IDEA IntellJ like this
Should remove all the white spaces in application.properties file. Then the test cases failed issue will be solved
I hope you have added dependencies now add spring.datasource.platform=h2 in your application.properties
it worked for me
These are the changes I made:
application-test.properties
spring.datasource.url=jdbc:h2:mem:testdb
spring.datasource.driver-class-name=
spring.datasource.username=
spring.datasource.password=
unsetting those datasource properties was only needed because I set them in the base application.properties. It'd be simpler just to not define them there and instead have them in the profile-specific properties, but leaving this here in case anyone else wants a quick/lazy fix
build.gradle.kts
testImplementation("com.h2database:h2")
                if you do this and leave the dependencyManagement section of the pom.xml as is the case w/ the pom.xml that is submitted w/ the question, it won't work.
