mvn install not creating jar files in the local repository

Question

I have a pom.xml file for my util direction, inside my project:

   <?xml version="1.0" encoding="UTF-8"?>
   <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
             xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
        <modelVersion>4.0.0</modelVersion>
        <parent>
            <groupId>com.myapp.app</groupId>
            <artifactId>MyApp</artifactId>
            <version>1.0-SNAPSHOT</version>
        </parent>

       <artifactId>util</artifactId>
       <packaging>jar</packaging>
       <version>1.0-SNAPSHOT</version>
       <name>Util</name>
       <url>http://maven.apache.org</url>
         ...
         <other things here>
       </project>

When I execute mvn clean install, it works fine. However, when I try to use that util dependency I get:

[ERROR] Failed to execute goal on project helloworld: Could not resolve dependencies for project com.myapp.app:helloworld:jar:1.0-SNAPSHOT: Could not find artifact com.myapp.app:util:jar:1.0-SNAPSHOT -> [Help 1]

Looking into ~/.m2/repository/ I don't see a util directory. Why is that happening? How can I have maven to install those packages in the local repository?

Solution

When you do mvn clean install, please take a look at [INFO] Installing line and see where it installs your package, maybe your config is wrong.

Log above shows that the package installed correctly. Please show us how you define dependency to utilize in hello world.

<groupId> is missing.

[Krzysztof Krasoń]

<groupId> is taken from parent, so it is not missing

[cybertextron]

@krzyk so I should also have a group id for the dependency?

[Krzysztof Krasoń]

@philippe please correct the name of the package, yoou write that it is utils but in the logs you provided it is util

[Krzysztof Krasoń]

@philippe <dependency> always has to have groupId (maven will scream if it doesn't), you don't need groupId in the above pom, because you inherit from parent which has groupId defined

[user2953113]

Are there any settings for maven-install-plugin in this pom or parent pom?

[cybertextron]

@user2953113 everything is working now ... but I know there's a problem there. The only thing different I did was mvn clean install -DskipTests -P-generateLicenses from the myapp directory

[cybertextron]

there isn't a [INFO] Installing step in the logs ... However I can find util-1.0-SNAPSHOT.jar in the ..util/target directory ... how can I fix that?

[user2953113]

It's the package phase that created the jar file in target directory. No need to fix it.

[JPS]

This is funny.. because there it is in your own log: Installing myapp/util/target/util-1.0-SNAPSHOT.jar to ~/.m2/repository/com/myapp/app/util/1.0-SNAPSHOT/util-1.0-SN‌​APSHOT.jar

[JPS]

btw, thank you @Krzysztof Krasoń the installing line showed me that i was installing to a different local repository. exact solution.
