Maven Snapshots Is Not Working I Do Not Think

Question

I am trying to follow this tutorial: http://www.tutorialspoint.com/maven/maven_snapshots.htm

I think I am running into problems with this though. When I run the pom.xml for the project in the myApp directory I receive the following output:

[INFO] Scanning for projects...

The WARNING message directly below [INFO] Building myApp 1 is what I think means that the myApp pom.xml is not successfully grabbing the latest SNAPSHOT for the other module it calls in its pom.xml.

The SNAPSHOT functionality should allow for another module to grab the latest version of the build for a different module that the first module depends on.

Below is my pom.xml for the first project, myApp , that depends on the latest version of another project.

<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>
  <groupId>com.companyname.appid</groupId>
  <artifactId>myApp</artifactId>
  <packaging>jar</packaging>
  <version>1</version>
  <name>myApp</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>

    <dependency>
      <groupId>com.companyname.bank</groupId>
      <artifactId>consumerBanking</artifactId>
      <version>1.0-SNAPSHOT</version>
      <scope>test</scope> 

    </dependency>

  </dependencies>
</project>

Now, below one will find the pom.xml for the consumerBanking project that the previous pom.xml for myApp depends on.

<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/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.companyname.bank</groupId>
  <artifactId>consumerBanking</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>jar</packaging>

  <name>consumerBanking</name>
  <url>http://maven.apache.org</url>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>

    <dependency>
       <groupId>c3p0-0.9.1.1</groupId>
       <artifactId>c3p0-0.9.1.1</artifactId>
       <scope>system</scope>
       <version>1.0</version>
       <systemPath>${basedir}\src\lib\c3p0-0.9.1.1.jar</systemPath>
    </dependency>


  </dependencies>
</project>

Does anyone know why I am receiving the WARNING? Does this mean the SNAPSHOT functionality is not working correctly? The message I am referring to is:

"The POM com.companyname.bank:consumerBanking:jar:1.0-SNAPSHOT is invalid, transitive dependencies (if any) will not be available, enable debug logging for more details"

Thank-you for reading all of this!

Regards,

me

Answer 1

I suppose Maven regards your dependency POM as invalid due to this section which does not make sense:

<dependency>
   <groupId>c3p0-0.9.1.1</groupId>
   <artifactId>c3p0-0.9.1.1</artifactId>
   <scope>system</scope>
   <version>1.0</version>
   <systemPath>${basedir}\src\lib\c3p0-0.9.1.1.jar</systemPath>
</dependency>
