I am using maven 3 to run the application but I am getting the following error:

[ERROR] The build could not read 1 project -> [Help 1]

I have the following child module pom file:

</project>

I tried commenting the below part in the parent pom file( i don't know if it is correct to do it), then this error is gone and the build fails with this error.

<parent>
<groupId>com.topdesk</groupId>
<artifactId>tis-parent</artifactId>
<version>3.4</version>
</parent>

Please help me!

Thanks

Answer 1

The normal layout for a maven multi module project is:

parent
├── pom.xml
├── module
    ├── pom.xml

Check that you use this layout.

Additionally:

1. the relativePath looks strange. Instead of '..'

   <relativePath>..</relativePath>
   

   try '../' instead:

   <relativePath>../</relativePath>
   

   You can also remove relativePath if you use the standard layout. This is what I always do, and on the command line I can build as well the parent (and all modules) or only a single module.

2. The module path may be wrong. In the parent you define the module as:

   <module>junitcategorizer.cutdetection</module>
   

   You must specify the name of the folder of the child module, not an artifact identifier. If junitcategorizer.cutdetection is not the name of the folder than change it accordingly.

Hope that helps..

EDIT have a look at the other post, I answered there.

Answer 2

I'm probably a bit late to the party, but I wrote the junitcategorizer for my thesis project at TOPdesk. Earlier versions indeed used a company internal Parent POM. So your problems are caused by the Parent POM not being resolvable, since it is not available to the outside world.

You can either:

• Remove the <parent> block, but then have to configure the Surefire, Compiler and other plugins yourself
• (Only applicable to this specific case!) Change it to point to our Open Source Parent POM by setting:

<parent>
    <groupId>com.topdesk</groupId>
    <artifactId>open-source-parent</artifactId>
    <version>1.2.0</version>
</parent>

Answer 3

There was conflict in java version. Resolved after using 1.8 for maven.

Answer 4

You can try with the following way,

 <parent>
    <groupId></groupId>
    <artifactId></artifactId>
    <version></version>
  </parent>

So that the parent jar will be fetching from the repository.

Answer 5

So In my case, After trying all the above options, I realized it was VPN (company firewall).once connected and ran cmd: clean install spring-boot:run. Issue is resolved. Step 1: check maven is configured correctly or not. Step 2: check settings.xml is mapped correctly or not. Step 3: verify if you are behind any firewall then map your repo urls accordingly. Step 4:run clean install spring-boot:run step 5: issue is resolved.
