Successfully installed 3rd party jar for Ojdbc5 in nexus

content of my parent pom

In the above pom.xml there are two projects define. When I build using jenkins, The first project get successfully build. but the second one throws error.

Failed to execute goal on project project2: Could not resolve dependencies for project com.abc:project2:war:0.0.1-SNAPSHOT: Failure to find com.oracle:ojdbc5:jar:11.2.0.1 in http://localhost:8081/nexus/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of nexus has elapsed or updates are forced -> [Help 1]

Please see the project2 pom.xml

    <!-- That is creating problem -->

Please do not worry about the above pom.xml I have removed lot of dependency from pom to reduce the size of question. The pom structure is Ok.

Now coming to question. Have I missed any configuration, Why I am getting

Failed to execute goal on project gsdataprocessor: Could not resolve dependencies for project com.globalss.batch:gsdataprocessor:war:0.0.1-SNAPSHOT: Failure to find com.oracle:ojdbc5:jar:11.2.0.1 in http://localhost:8081/nexus/content/groups/public was cached in the local repository, resolution will not be reattempted until the update interval of nexus has elapsed or updates are forced -> [Help 1]

This error. Please help

Update 1: As suggest by user sanigo I have added Thirdpary repository the Public Repository Group

Update 2: Below is the screen-short which shows oracle ojdbc5 is available is public repository.

Answer 1

Your http://localhost:8081/nexus/content/groups/public (Public Repository Group) is mirror of "*", so you should add http://localhost:8081/nexus/content/repositories/thirdparty(Thirdparty repositoy) to the Public Repository Group, you can do this in the Public Repository Configuration tab. Then you can use mvn -U clean install.
