Dear Wiki user, You have subscribed to a wiki page or wiki category on "Cassandra Wiki" for change notification.
The "RunningCassandraInEclipse" page has been changed by RogerSchildmeijer. http://wiki.apache.org/cassandra/RunningCassandraInEclipse?action=diff&rev1=1&rev2=2 -------------------------------------------------- Eclipse is open source. Download Eclipse from http://www.eclipse.org/downloads/. There is no need for the Enterprise Edition (EE) version of Eclipse. Hence "Eclipse IDE for Java Developers" is good enough. - Cassandra is using Git and Subversion for version control. In this tutorial we will checkout Cassandra from subversion. To be able to do this we need a subversion plugin for Eclipse, because there is no native svn (or git) support. Feel free to use your favorit Eclipse Subversion plugin. Though this tutorial will use the Subclipse (http://subclipse.tigris.org/) Ecplise Subversion plugin. + Cassandra is using Git and Subversion for version control.

Subclipse or Subversive) + + {{attachment:WindowOpenPerspectiveOther-1.png}} + + Right mouse click in the "SVN Repositories" view, choose New -> Repository Location... + Enter https://svn.apache.org/repos/asf/cassandra/ as the Url and the press "Finished".

Press "Finish" without do any changes. If the IDE asks you to open the "Java Perspective" I recommend you you to do so. Also if the "Confirm Overwrite" dialog appears just accept. + + {{attachment:NewJavaProject-6.png}} + + After the following steps your project workspace should look something like this: + + {{attachment:InitialEclipseProjectWorkspace-7.png}} + + As you might have noticed (currently) Eclipse is mad and we need to perform some additional steps (generate CLI (Command Line Interface) grammar, avro, thrift and add some third party dependencies to the Eclipse build path (java classpath)) to fix this. + + Right click on the build.xml (in your project root) -> Run As -> Ant Build + This will do a whole lot of good things, eg. generate the CLI grammar with ANTLR, generate avro and thrift code. + + Next thing you want to do is to add all the needed third party libraries to the build path. + Expand the lib/ folder and find a bunch of jar files. Shift select all of them and right mouse click and choose "Build Path" -> "Add to Build Path". + This will force Eclipse do update the entire workspace, so please be patient. Some of the errors should also have disappeared by now (not all though). + + {{attachment:AddToBuildPath-9.png}} + + The final step is to add the generate Java code to the Eclipse build path. Expand and select interface/thrift/gen-java, right click -> "Build Path" -> "Use as Source Folder". Do the same for interface/avro/gen-java and src/gen-java. + + {{attachment:AddThriftToBuildPath-10.png}} + + Now the errors should be gone and you are ready to create a run/debug configuration for cassandra. + + Click "Run" -> "Run Configurations...". Select org.apache.cassandra.thrift.CassandraDaemon as you Main class, make sure that your cassandra project is select in the "Project" field. + Under the Arguments tab you can specify VM arguments.
