SBT-Giffy a simple web based tool to create sbt files for scala projects

 - 18/5/2013   3 days ago

Recently I was trying something with AngualrJS for one of my official assignments while studying its features I got an idea to develop an UI for creating SBT build files and that SBT-Giffy. 

The idea of sbt giffy is to capture the very basic details which goes in to the build.sbt file in an web based UI. SBT-Giffy provides a nice way to specify the dependencies by capturing groupId, artifactId and version with a typeahead text fields and as many as dependencies could be defined, I believe this would eliminate the pain for developers from searching through the maven repository. 

Once defined , SBT-Giffy generates the build.sbt file could be previewed which in turn could be copied to create a build.sbt file.

As of now this is a pet project and is hosted in github here.

Some of the features that are coming up 

> capture JAVA_OPITONS

> multi-project builds 

> define custom maven repositories. 

> support for creating giter8 templates 

>  improve the UI !!!

Tip :- Allocate memory for SBT through _JAVA_OPTIONS variable

 - 3/4/2013   1 month ago

Recently I was working with sbt and ran in to an issue. My sbt was not proceeding further to build code it said : 
 > sbt 

Error occurred during initialization of VM 
Could not reserve enough space for object heap 
Error: Could not create the Java Virtual Machine. 
Error: A fatal exception has occurred. 
Program will exit. 

The root cause was java could not allocate enough memory to start sbt.After googling I found that we can set an environment variable to allocate memory space using the _JAVA_OPTIONS variable. 

> _JAVA_OPTIONS="-Xms512M -Xmx1024M -Xss1M -XX:+CMSClassUnloadingEnabled" sbt 

since it doesn't make sense to issue the _JAVA_OPTIONS I went ahead to append those to my ~/.bashrc so that I get that executed every time I login. 

If your ever face such issues with sbt make feel free to make of this tip :-)
