Maven does not read POM when installing JAR to repository

Question

I've followed the guide here to install a JAR file into my local repository.

I run following command:

mvn org.apache.maven.plugins:maven-install-plugin:2.5.2:install-file -Dfile=log4j-weblayout-0.0.1-SNAPSHOT.jar

The JAR file is built using Maven and contains a POM file inside it listing its dependencies. The file inside JAR has the path:

/META-INF/maven/in.ksharma/log4j-weblayout/pom.xml

Maven installs the artifact but does not read its POM. It creates an empty POM file which is void of any dependency info:

<?xml version="1.0" encoding="UTF-8"?>
<project xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd" xmlns="http://maven.apache.org/POM/4.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <modelVersion>4.0.0</modelVersion>
  <groupId>in.ksharma</groupId>
  <artifactId>log4j-weblayout</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <description>POM was created from install:install-file</description>
</project>

How can I ensure that the POM inside the JAR is the one that is installed?

Edit:

Contents of various files inside the JAR are as follows.

/META-INF/MANIFEST.MF:

Answer 1

I think you'll need to extract the pom.xml from the jar and specify it using the pomFile property as follows:

mvn org.apache.maven.plugins:maven-install-plugin:2.5.2:install-file -Dfile=log4j-weblayout-0.0.1-SNAPSHOT.jar -DpomFile=pom.xml

Answer 2

Seems to be fixed in 3.0.0-M1 version of install plugin, but maven might still use 2.5.2 as a default. You can set the version of the install plugin in your pluginManagement section:

  <pluginManagement>
      <plugins>
      ...
        <plugin>
          <groupId>org.apache.maven.plugins</groupId>
          <artifactId>maven-install-plugin</artifactId>
          <version>3.0.0-M1</version>
        </plugin>
      ...
      </plugins>
  </pluginManagement>

or call the right version of the plugin on the command line:

mvn org.apache.maven.plugins:maven-install-plugin:3.0.0-M1:install-file -Dfile=log4j-weblayout-0.0.1-SNAPSHOT.jar
