How to develop on gricli

Getting the souce code

Recommended way to contribute is to fork the gricli repo (https://github.com/grisu/gricli) and then clone your remote repo, something like:

git clone git@github.com:makkus/gricli.git

If you have Eclipse setup with the m2eclipse plugin, you can just import gricli as maven project via:

File -> Import... -> Maven -> Existing Maven Projects

and point Eclipse to the root gricli directory.

Once you made changes and want those to be included into the gricli project, just send a pull request via github.

Building

In order to build gricli you need to have Java and Maven installed on your development machine. Once that is ready, just

mvn clean install

and you have a ready-to-use gricli-binary.jar in the target/ directory.

Executing directly

The gricli main class is:

grisu.gricli.Gricli

You can either start that with in your IDE (although that sometimes causes issues since the Console that comes for example with Eclipse does not support advanced features like tab-completion) or execute it via maven:

mvn exec:java -Dexec.mainClass="grisu.gricli.Gricli" -Dexec.classpathScope=compile

or

mvn exec:java -Dexec.mainClass="grisu.gricli.Gricli" -Dexec.classpathScope=compile -o -Dexec.args="-b Local"

to run it with a local backend and set maven to be offline (which means it doesn't try to download dependency updates).

Running gricli using maven but debug via Eclipse

First, we export remote debug parameters via maven:

export MAVEN_OPTS="-Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=1044"

then we run gricli:

mvn exec:java -Dexec.mainClass="grisu.gricli.Gricli" -Dexec.classpathScope=compile -o -Dexec.args="-b BeSTGRID-TEST"

Then we create -- if not already created -- an Eclipse "Remote Java Application" in the "Debug Configurations", set port to 1044. This we run via Eclipse debug options. Now we are able to debug stuff like tab-completion :-)

Including JRebel

First, we need to export the jrebel javaagent to maven:

 mvn exec:exec -Dexec.executable="java" -Dexec.args="-javaagent:/opt/JRebel4/jrebel.jar -classpath %classpath grisu.gricli.Gricli" -o -Dexec.classpathScope=compile

Doesn't work for me though, since it seems gricli can't access the console anymore with this... :-(
