maven plugin install:install-file error

Question

I use install:install-file to install jar to my local repository.My pom.xml is written as follow:

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<version>2.3.1</version>
<executions>
    <execution>
    <id>install-paho</id>
    <phase>generate-resources</phase>
    <goals>
        <goal>install-file</goal>
    </goals>
    <configuration>
        <file>${basedir}/lib/paho.jar</file>
        <groupId>org.eclipse</groupId>
        <artifactId>paho</artifactId>
        <version>1.0.0</version>
        <packaging>jar</packaging>
    </configuration>
    </execution>
</executions>
</plugin>

You can find that I binding it to phase 'generate-resources'.And then,I use order mvn eclipse:eclipse.It works very well and the jar was copied to my local repository.But when I use order mvn install:install-file I got the error:

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-install-plugin:2.3.1:install-file (default-cli) on project xxx: 
The parameters 'file' for goal org.apache.maven.plugins:maven-install-plugin:2.3.1:install-file are missing or invalid -> [Help 1]

The error messages when use mvn compile

[ERROR] Failed to execute goal on project android-engine: Could not resolve dependencies    for project com.youku.wireless:android-engine:jar:1.0-SNAPSHOT: Could not find artifact org.eclipse:paho:jar:1.0.0 in spring-milestone (http://maven.springframework.org/milestone) ->   [Help 1]

Answer 1

Since you have bound install:install-file goal to the generate-sources phase, you should run mvn compile or mvn install or such to use the defined configurations.

mvn eclipse:eclipse works because maven runs the generate-sources phase prior to invoking eclipse:eclipse.

Edit: From the comments it looks like you want to use the locally available paho.jar in your project by first installing it to your local repo in the generate-sources phase and thereafter use it as a dependency in your project.

This is not going to work since maven checks for availability of dependencies before it starts executing its life-cycle goals.

You could manually install it one-time using mvn install:install-file outside the context of the pom. Better still you could deploy it to a repository manager and then access it like any other dependency.

However, if you still want to go down this path, an alternate approach would be to specify the dependency with a system scope providing the path of the jar. Refer to this.

<project>
  ...
  <dependencies>
    <dependency>
      <groupId>org.eclipse</groupId>
      <artifactId>paho</artifactId>
      <version>1.0.0/version>
      <scope>system</scope>
      <systemPath>${basedir}/lib/paho.jar</systemPath>
    </dependency>
  </dependencies>
  ...
</project>
