maven cache in pipeline seems not working

[Zhenguo Li]

I have added below script in pipeline, but it seems not working , every build take more than 30 min for mvn install , any problem recently for this cache function ?

image: maven:3.6.3

pipelines:

  branches:
    develop:
      - step:
          name: Build and Unit Test
          artifacts:
            - x_api/target/x_api.jar
            - checkstyle-result.xml
          image: maven:3.6.3
          caches:
            - maven
          script:
            #- mvn -B verify --file pom.xml
            - cd x_api
            - mvn install
            - mvn package --batch-mode
            - cd ../x_service
            - mvn install
            - mvn package --batch-mode

 thank you,

Hi Jonas,

I just wanted to let you know that we have a limit of 1GB for caches, only caches under 1GB once compressed are saved.

Maven cache is saved in the directory ~/.m2/repository, so I would suggest checking the size of this directory during the build and after dependencies are downloaded.

If the repo belongs in a workspace with a paid billing plan (I see you are an admin of such a workspace), you can also create a ticket with the Bitbucket Cloud support team to look into this and confirm if the issue is with the cache size or something different. You can create a support ticket via https://support.atlassian.com/contact/#/, in "What can we help you with?" select "Technical issues and bugs" and then Bitbucket Cloud as product.

Kind regards,
Theodora

I saw below in pipeline log

Cache "maven": Not found

is there any limit like size of the maven cache , possible exceed the limit cause maven was not cached

i can't paste full log here, it just said there is no cache for maven in build setup step.

and there is no any cache shows if I click the Cache button on pipeline's home page.

[lissyaka]

@Zhenguo Li. To check if maven cache working or not you should try to run pipeline this example repo

If cache is not working its definitely a bug and you may report it.

If cache is working then problem is in your `script section`. I think the reason is that you changing folders and then run `mvn install` when your cache possibly is in upper folder, but i can be wrong.

Look at this answer to understand how to define cache for custom folder

P.S also you do not need

image: maven:3.6.1

in `step` section because you use

image: maven:3.6.3

in the beginning of your pipeline config. I understand that i suggested you to do it but also it explains why i asked you to provide the full pipeline config to provide better help.

Cheers

Hi @Zhenguo Li . At least you should add more details about your pipeline config.

Also take a look at this answer: maven cache not working .
There

image: maven:3.6.1  

was added before caches, maybe this will fix your issue.

Cheers
