In this post I’ll show you how to use a Maven archetype – or more specifically the TrueVFS Archetype Access – to generate a bunch of sample applications for TrueVFS. I’m using NetBeans 7.2 for this post, but similar actions apply to Eclipse, IntelliJ IDEA or whatever, so please read on.

Fire up NetBeans and select File -> New Project…:

In the upcoming dialog, select Maven -> Project from Archetype and click Next:

On the next tab, enter the group-id net.java.truevfs, the artifact-id truevfs-archetype-access, the version 0.9.1 and click Next:

On the next tab, accept the default property values and click Finish. In the output window, you should see something like this:

cd C:\Users\christian\Documents\NetBeansProjects; "JAVA_HOME=C:\\Program Files\\Java\\jdk1.7.0_07" "M2_HOME=C:\\Program Files\\Apache Software Foundation\\apache-maven-3.0.4" "\"C:\\Program Files\\Apache Software Foundation\\apache-maven-3.0.4\\bin\\mvn.bat\"" -DarchetypeGroupId=net.java.truevfs -DarchetypeArtifactId=truevfs-archetype-access -DarchetypeVersion=0.9.1 -DarchetypeRepository=local -DgroupId=com.company -DartifactId=mavenproject1 -Dversion=1.0-SNAPSHOT -Dpackage=com.company.mavenproject1 -Dbasedir=C:\\Users\\christian\\Documents\\NetBeansProjects -Dtruevfs-version=0.9.1 -Dscala-version=2.9.2 -Darchetype.interactive=false --batch-mode archetype:generate<br />Scanning for projects...

Next, right click on the generated project and select Set as Main Project. Right click again and select Properties -> Run. In the upcoming dialog, click Browse next to the text field for the main class and select com.company.mavenproject1.java.diagnostics.DriverMap2Html:

Now simply press Run Main Project (F6 on Windows). In the output window, you should see something like this:

What happened is that the DriverMap2Html class scans the class path for all file system driver modules and prints the resulting mapping to HTML. This may come in handy for diagnosing the “Heck, why wasn’t my archive file recognized by TrueVFS?” class of issues.

That’s it for now. Next time we’ll take a look at some statistics provided by the TrueVFS Kernel. Meanwhile you may want to explore the generated archetype. For an explanation of what’s inside, have a look at http://truevfs.java.net/kick-start/file/netbeans.html#Explore_Your_Sample_Applications
