Is it best to Mavenize your project jar files or put them in WEB
I've been doing this for all of the jar files that my Spring MVC project needs:
call mvn install:install-file -DgroupId=vegetables -DartifactId=potatoes -Dversion=1.0 -Dfile=vegetables-1.0.jar -Dpackaging=jar -DgeneratePom=true
Recently I must have exceeded some limit on how many dependencies you can list in your pom.xml file because I got an error that said:
Your command line is too long
So I removed some dependencies from the pom.xml that my project no longer uses and I was able to run the project with maven again.
My question is, should I put install all jar files into my Maven repository as I have been doing so far? Or should I put some of them into the WEB-INF/lib directory?
What's the best practice here?
I've been doing the same that you do with the command line, but by configuring maven-install-plugin in my POM (please read the note at the end):
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-install-plugin</artifactId>
<executions>
<execution>
<id>install-vegetables</id>
<phase>initialize</phase>
<goals>
<goal>install-file</goal>
</goals>
<configuration>
<file>${project.basedir}/lib/vegetables-1.0.jar</file>
<groupId>vegetables</groupId>
<artifactId>potatoes</artifactId>
<version>1.0</version>
<packaging>jar</packaging>
</configuration>
</execution>
<execution>
<id>install-minerals</id>
<phase>initialize</phase>
<goals>
<goal>install-file</goal>
</goals>
<configuration>
<file>${project.basedir}/lib/minerals-1.0.jar</file>
<groupId>minerals</groupId>
<artifactId>rocks</artifactId>
<version>1.0</version>
<packaging>jar</packaging>
</configuration>
</execution>
</executions>
</plugin>
It is much less efficient, because files get installed over and over, but it is much less annoying than making it manually. Anyway, I think you should give it a try.
All your dependencies should reside under the local repository. According to the Maven convention/best practices, you should not keep jar files in your project.
Convert your project to a fully war based Maven project. This will place all your dependencies (jar files) under your webapp's WEB-INF/lib directory. Thus you will not have to worry about long paths.
You just need to add the dependencies in your pom.xml file, no need to install them manually. Maven will download the libraries and put it in your local repository whenever needed. Only if you want to use third party(custom) libraries, you may go for installing it in your local repository.
