Maven caching does not work

Sandhya Banwarie

I have created a simple bitbucket-pipeline.yaml

The caching maven does not work. Build time is almost 1 hour. What am i doing wrong here? Adter build is succesful i don't see any cache in pipeline created?

 

image: maven:3.6.3

pipelines:

branches:

CSO_pipelines:

- step:

name: Docker build and clean install

caches:

- maven

script:

- mkdir -p "$BITBUCKET_CLONE_DIR/.m2"

- mvn -B -s settings.xml compile

definitions:

caches:

maven: .m2

Hello @Sandhya Banwarie  and welcome to Atlassian Community!

I see that in your cache definition you configured the maven cache to the folder .m2, however, when you provide the folder in that format, it will be relative to the clone directory (the directory where your repository is cloned inside the container) and maven is not saving the dependencies in that folder.

In this case, I would suggest changing the path in your cache definition to ~/.m2/repository which is the default location where Maven will download them : 

definitions:
  caches:
    maven: ~/.m2/repository

If you haven't changed the maven default dependencies path, the definition above should create a cache from the dependencies downloaded during your build.

Also, since maven is one of the available pre-defined caches in bitbucket pipelines , you don't actually need the definition above when using the maven default location, because when you configure a cache named maven in your step, it will already point to the ~/.m2/repository directory. You can check the other pre-defined caches for common language tools at the following link :

Thank you, @Sandhya Banwarie !
