Prabin, The error log says that it can't find the parent pom file specified in the agentj-core module in your source. Since maven can't find the pom file in remote repositories, I assume you have the parent pom file included in your source. So, look for the pom.xml file with both groupId and artifactId equals to 'agentj'. Then, make sure you have the needed version, ie 1.0.
It probably looks like the version in the agentj:agentj's pom.xml is 1.1, while the agentj-core module refers to the 1.0 version. If that's the case, you'll have to change the 1.0 to 1.1 in the a-core's pom. I can't predict without seeing the groupId/artifactId/versions of the pom files of the project! --Kasun On Wed, Jul 27, 2011 at 4:02 PM, prabin <[email protected]> wrote: > hello everybody, > > I am very new in using and installing maven.
