Non-resolvable parent POM: Could not find artifact

[Hanan2]

Hello there

i downloaded Pellet zip folder and I tried to run the maven project but I could not choose "main class". Also, when I run the project, I got the following run error.

The build could not read 1 project -> [Help 1]

The project com.clarkparsia.pellet:pellet-owlapi:2.4.0-SNAPSHOT (/Users/han/NetBeansProjects/pellet-master/owlapi/pom.xml) has 1 error Non-resolvable parent POM: Could not find artifact com.clarkparsia.pellet:pellet-parent:pom:2.4.0-SNAPSHOT and 'parent.relativePath' points at wrong local POM @ line 4, column 10 -> [Help 2]

To see the full stack trace of the errors, re-run Maven with the -e switch. Re-run Maven using the -X switch to enable full debug logging.

For more information about the errors and possible solutions, please read the following articles: [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/ProjectBuildingException [Help 2] http://cwiki.apache.org/confluence/display/MAVEN/UnresolvableModelException

How can I solve this problem in order to run the project properly?

I don't get the same failure. I had an error saying a certain OWLAPI version was not available.

In the root pom, locate this line:

    <owlapi.version>[4.0.2,4.2)</owlapi.version>

This is a range version number, and is not resolved properly. Set it to a specified version, such as 4.2.8 (that's the OWLAPI version used in many Protege versions). That worked for me, compiling from the command line with

mvn clean test

when you download Pellet master folder, which maven project did you run? because the folder has several maven projects. also, when I select for example "owlapi" maven project to open and run in netbeans, I got "unloadable" text next to "owlapi" in projects list. There is any problem with opening the project? or are there any specific way to open and run the project.?

when you download Pellet master folder, which maven project did you run?

There is a pom.xml file in the root. That's the root project, the rest are its modules. You cannot build one module outside the context of the root project.

Sorry for this question but I am new to maven projects and this projects have several sub maven projects. I searched in Pellet-master folder about "pom.xml" file and I found 14 pom.xml files. I am confused, Could you please tell me thankfully in which directory/folder the root pom.xml is available?

[ignazio1977]

The root (or parent) pom.xml file is in the pellet-master folder - same folder as the owlapi folder.

when I run root POM, I got this error. How can I fix it.

That compile issue existed in an ancient Pellet version. The current master has:

 public boolean remove(Object key, Object value) {
    boolean removed = false;

    Set<V> values = get( key );

This will compile successfully.

thanks for your suggestion. The project has been built successfully in Eclipse.

I have a question plz, I would like to run one file at a time from example module. how could I run/compile a specific java file in the project.?
