← ALL HOW TOs

Generate jar/war

• Edit pom.xml
• Set Packaging to either jar or war
• Save pom.xml
• Rt click pom.xml
• Select Run as... -> Maven Install
• Look in target directory for *.jar or *.war

Reload all dependencies in pom.xml

• Rt click pom.xml -> Run as -> Maven install

Run all steps of Maven

• Rt click pom.xml -> Run as -> Maven build
• Select package (May need to select something else. Not exactly sure why package is the right thing to select. Got this info from Matt.)

Open an SVN project as a Maven project in Eclipse

In Windows Explorer

• Navigate to Eclipse working directory
• Rt Click -> SVN Checkout...
• Use ... browse button for URL of repository to select project to checkout.
• Click OK

In Eclipse

• File -> Import...
• Select Maven -> Existing Maven Projects
• Browse... to project in Eclipse working directory
• select trunk
• OK
• Finish

Creating a local repository holding jars not available in a public repository

Assumptions

• The jar was created by Maven in another project with the following

  <groupId>edu.cornell.clo</groupId>
  <artifactId>messageQueue</artifactId>
  <version>0.4.1</version>
  <packaging>jar</packaging>

In Project (that wants to access the jars)

• create repo directory just off the project base directory
• for each jar to be accessed locally

  • add directories for each level of the groupID (ex. /repo

    <b>/edu/cornell/clo/</b>

    )

  • add jar name (aka artifactId) without the version (ex. /repo/edu/cornell/clo

    <b>/messageQueue</b>

    )

  • add directory for the version of the jar (ex. /repo/edu/cornell/clo/messageQueue

    <b>/0.4.1</b>

    )

  • put the jar in that directory (ex. /repo/edu/cornell/clo/messageQueue/0.4.1

    <b>/messageQueue-0.4.1.jar</b>

    )

In POM (for the project that wants to access the jars)

• define the local repository

  <repositories>
    <repository>
      <id>data-local</id>
      <name>data</name>
      <url>file://${project.basedir}/repo</url>
    </repository>
  </repositories>

• add the dependency on the local jar

  <dependency>
    <groupId>_package-path_</groupId>
    <artifactId>_jar-name-without-version_</artifactId>
    <version>_version_</version>
  </dependency>

From our example above, this would be...

  <dependency>
    <groupId>edu.cornell.clo</groupId>
    <artifactId>messageQueue</artifactId>
    <version>0.4.1</version>
  </dependency>
