Maven Install plugin: parameter file is missing or invalid

Question

I have a local jar and I want to use it in my project. There are plenty ways to do it: just install manually into local repo, do it with script in parent pom, use system scope, use local repo declaration.

I decided to use Maven Install plugin to install jar into the repo. Here is a configuration:

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-install-plugin</artifactId>
        <version>2.3.1</version>
        <executions>
            <execution>
                <phase>initialize</phase>
                <goals>
                    <goal>install-file</goal>
                </goals>
                <configuration>
                    <groupId>jacob</groupId>
                    <artifactId>jacob</artifactId>
                    <version>1.0</version>
                    <packaging>jar</packaging>
                    <file>${basedir}\lib\jacob.jar</file>
                </configuration>
            </execution>
        </executions>
    </plugin>

I tried to run it in many ways: mvn initialize install:install-file mvn initialize mvn install:install-file

But all the time I have an exception:

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

I just want to find out why it doesn't work? Looks like I am messed with phases and goals..

Finally I went another way: I placed it into my parent POM, but why it works with parent and doesn't work with child?

Answer 1

The best way to deal with a separated jar is to start using a repository manager and install this jar via the UI into the repository manager. From that point you can use as a usual dependency. Makes life easier.

If you like to install it as part of the build what you have tried that means you need to call maven like this:

mvn package

You should not mix up calling goals without life cylce like install:install-file with life-cycle parts as initialize.

That is the reason why you got the described error message, cause the command line part needs required parameters which you didn't gave on command line.

Combination like:

mvn install:install-file initialize

Make in Maven no sense (rarly). You have bound the maven-install-plugin to the life-clycle in your pom so you should simply call the life cylce:

mvn initalize

And you will get something like the following:

BUT: I have to say that installing an artifact like you did is bad practice. Best is to use a repository manager like Nexus, Artifactory or Archiva or if really don't like repository managers (I don't understand why, but this is a different story) you can use Stephen Connolly's non-maven-jar-maven-plugin

Apart from all the above you should use more up-to-date versions of maven-install-plugin which current version number is 2.5.2
