Slow gitlab pipeline

Question

I've configured a pipeline for maven/java/spring project using a local gitlab-runner in my Mac. My project is hosted on gitlab.com. At every commit, it always takes forever, because it downloads all the dependencies.

Using the shared gitlab-runner the build and test is faster, but it uses my quota minutes. How can I improve it using local gitlab-runner? I can't wait 1 hour at every run.. Thanks in advance!

Same for the other jobs , release, test - docker push - deploy

My gitlab-pipeline is (just showing build and test jobs)

I'm using JIB to build the image and this is the maven plugin configuration

<plugin>
    <groupId>com.google.cloud.tools</groupId>
    <artifactId>jib-maven-plugin</artifactId>
    <version>${google.jib.version}</version>
    <configuration>
        <container>
            <creationTime>USE_CURRENT_TIMESTAMP</creationTime>
        </container>
        <from>
            <image>openjdk:17-jdk-slim-buster</image>
        </from>
    </configuration>
    <executions>
        <execution>
            <id>Skip-build-on-release</id>
            <phase>none</phase>
        </execution>
    </executions>

Finally this is the config.toml
