I think you need to restart the repl before any new dependencies will
be added to the classpath, and then you need to import them in the
repl if you haven't already done so in the file you loaded into the
repl. There's an arrow on the toolbar on the side of the repl window
that resets it.

I don't think the "Run Main Project" stuff works with enclojure (if it
does you must need to tweak a few things). I generally do most of my
development with a repl running (so lots of alt-L, alt-shift-N, call
the function, rinse wash repeat), then when I want to deploy I add the
appropriate maven directives to the pom to create a runnable jar file
(using the jar and dependency plugins), which means I can do java -jar
<jarfile> and it runs. If that is the kind of thing you're looking for
give me a yell and I'll send some examples.

Very much a clojure noob though so not sure if that is a typical workflow.

Hi Steve,

I was also trying to get things going in a similar way (i.e. develop with
netbeans/enclojure/repl and then generate a stand alone jar) - after the build I
could not run the executale jar (could not find main class). I would be happy if
you can provide an example that worked for you.

Thanks,
Douwe

Create a clojure project with the following clojure file in package
"bar":

(ns foo.bar
(:gen-class))

(defn -main []
(println "Looks like it works"))

Then add the following to the pom in the plugins section:

<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>foo.bar</mainClass>
<classpathPrefix>dependency</
classpathPrefix>
</manifest>
</archive>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-dependency-plugin</artifactId>
<executions>
<execution>
<id>copy-dependencies</id>
<phase>package</phase>
<goals>
<goal>copy-dependencies</goal>
</goals>
</execution>
</executions>
</plugin>

Run "mvn clean install", then "java -jar target/sample-0.0.1.jar" and
hopefully it will work.

The first plugin sets a main class in the manifest, and includes jars
from the "dependency" directory in the classpath.
The second plugin copies the dependencies into the "dependency"
directory in the "target directory.

Thanks very much, "looks like it works" (I created a package foo
instead of bar).

Now I can just hit Shift+F11 to clean + built the jar file.
