cannot serve about jnxplus

[asinkxcoswt]

Do I need to execute the mvn clean install -N only once? E.g. after creating a workspace with yarn create nx-workspace ..., etc.

I am not an expert and don't know much about how maven works internally. But as I inspect its behaviors, I found that the parent installed artifact ~/.m2/repository/your/package/{parent_artifact_id}/{version}/{parent_artifact_id}-{version}.pom contains the list of child modules. If you add a new module and don't re-install the parent pom, this file will not include your new module. Despite that, I have tested adding a new module

nx generate @jnxplus/nx-boot-maven:library --name "my-new-lib" --language java --groupId com.mycompany --projectVersion 1.0.0 --projects "my-app"

and then rebuild my-app without installing the parent artifact.

nx build my-app

It turns out my-new-lib and my-app can build properly without problem. So I think it is not neccessary to re-install parent, but I really don't know if it will break in other scenario.

For my project, my team has decided to always re-install the parent project when

1. After cloning the source code. (e.g. after running npm install).
2. After adding a new module.
3. Always re-install in CI pipeline

@vladimirdrayling now the build should work without running mvn clean install -N. Check the version 1.5.1

Hi @vladimirdrayling Thank you for raising this. You need to build api before serving it.
The api build will also build deps.
I will check if the serve can depends on the build. Like that we will not need to build.

Hi, could it be related to the problem mentioned in this stackoverflow answer?: https://stackoverflow.com/a/19525334/1078986

I got the same error and can fix by running mvn clean install -N once on the root directory.

What is missing is the artifact for the parent project. After running command above you will find ~/.m2/repository/your/package/{parent_artifact_id} is populated.

Hi @khalilou88 :)

After clearing node_modules/.cache and running nx build api, it didn't built the api. I got this error:

Can you please provide nx.json content?

[khalilou88]

the nx.json file has the part about building deps:

  "targetDependencies": {
    "build": [
      {
        "target": "build",
        "projects": "dependencies"
      }
    ]
  },

Really, I don't see any problem, try with nx build api --skip-nx-cache
Try to run mvn command directly
You can also share a repo, so we can look together

[draylegend]

Unfortunately I didn't get it to work :( So here is the repo

[khalilou88]

Could you remove the two tests files from api and test again.
Or remove this deps

    <dependency>
      <groupId>com.h2database</groupId>
      <artifactId>h2</artifactId>
      <scope>runtime</scope>
    </dependency>

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

    <dependency>
      <groupId>mysql</groupId>
      <artifactId>mysql-connector-java</artifactId>
      <scope>runtime</scope>
    </dependency>

nx test api didn't work.
the real error is a conflict between deps that you added. maybe you need a database..

@asinkxcoswt I'm a newbie regarding java. But your suggestion worked out! Thank you!

Also thank you @khalilou88 for the help! Together you helped to get this to work! :)

Do I need to execute the mvn clean install -N only once? E.g. after creating a workspace with yarn create nx-workspace ..., etc.

@khalilou88 is there a way to integrate the command into init process of your lib?

[khalilou88]

@asinkxcoswt @vladimirdrayling Maybe we can add mvn clean install -N before buildings apps.
Somthing like mvn clean install -N && mvn package spring-boot:repackage -DskipTests=true -pl :api
I need to be sure it's not expensive as an operation.

[draylegend]

Unfortunately I'm not a maven spring boot expert, so I can't really answer your question
