Hey Ram A,

Do you happen to have the SDK folder opened as a project inside of eclipse but happen to have it closed? If so can you either open the project or delete it (and don't delete the contents) and try again?

Hey Ram A,

Do you happen to have the SDK folder opened as a project inside of eclipse but happen to have it closed? If so can you either open the project or delete it (and don't delete the contents) and try again?

Hi Gregory,
Thanks for the reply.

I haven't opened the Liferay plugin SDK folder as a project in eclipse.
Itried to create a theme but it gave the same error.

And then i opened the SDK folder as project in eclipse(by selecting the checkbox infront of "open in eclipse" while configuring the plugin sdk) and the again i tried to create the theme.But agian it gave the same error.

Please help me.

Thanks in advance

Do you have any other projects open that happen to link or include the files that are in the SDK folder?

Another alternative is for you to create the theme project manually using the create.sh in the themes folder of the SDK using the command line tool in the SDK. Then you can import this into Eclipse using the "New Liferay Project from existing Source" wizard, or the import liferay project from existing source wizard (same wizard just with two names). Sorry but this is only workaround that I know of right now.

Hi Gregory,

Thanks for the help.
As you mentioned i created a Liferay theme manually using create.bat command in the themes folder of the sdk plugin using the command line tool.
And i imported the theme into eclipse using "New Liferay Project from existing source" wizard.

I am using Liferay Server v6.1.0-CE with tomcat-7.0.23 and liferay-plugins-sdk-6.1.1.
I tried to build and deploy the theme using plugin sdk in eclipse.
Then i got the below error .
Task cannot continue because ECJ is not installed.
ECJ was automatically installed. Please rerun your task.
I added the ecj jar in Apache ant lib folder and configured the Ant plugin (Ant-Home) in eclipse and again i tried to build it.
it was giving the below error.

I tried to build the theme using ant command (ant deploy) also.
It gave me the same error.

I checked the auto deploy folder of liferay server and dist folder in plugin sdk .The war created was there but it is not deploying from auto deploy folder.

Am a using wrong versions of plugin sdk and liferay server?
Is it because of those wrong versions.

Please anyone help me to resolve this issue.

Thanks in advance
