SpringBoot Maven build fails

Question

I'm new to maven. However, I'm trying to use Gitlab CI Runner for automated testing and building / deployment.

I got my current maven configuration from a colleague of mine.

When ever a job runs, it fails after a couple of seconds with following error message:

Downloaded: https://repo.maven.apache.org/maven2/org/springframework/security/spring-security-bom/4.2.3.RELEASE/spring-security-bom-4.2.3.RELEASE.pom (5 KB at 101.0 KB/sec)

Here are my spring dependencies:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.9.RELEASE</version>
</parent>

<dependencies>
    <dependency>

    </dependency>

    <dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-jpa</artifactId>
    </dependency>
</dependencies>

I appreciate any help, I couldn't find a solution for my error :/

Thanks a lot!

Answer 1

I think you mean

<!-- 
https://mvnrepository.com/artifact/org.springframework.boot/spring-boot
-configuration-processor -->
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-configuration-processor</artifactId>
</dependency>

not spring-boot-starter-processor , check it out here: https://mvnrepository.com/artifact/org.springframework.boot/spring-boot-configuration-processor/1.5.9.RELEASE

Answer 2

It looks like the root issue you are having is attempting to use a dependency that does not exist ( spring-boot-starter-processor from org.springframework.boot ). Fixing the dependency name to the one that is actualy defined in your parent - spring-boot-starter-parent will also fix your "version" problem.

The error you are seeing is saying a different thing (no version defined) because each maven dependency needs to have a version defined directly or in the dependency management. Since you have set up spring-boot-starter-parent as a parent, it uses dependency versions for all valid dependencies from there.

If for any reason this is a correct dependency name (which would be very strange), you will fix the error by properly defining the version, like:

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-processor</artifactId>
    <version>(insert version here)</version>
</dependency>

or via dependency management: https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#Dependency_Management
