I am trying to build protege-server (https://github.com/protegeproject/org.protege.owl.server) from source. I downloaded the source code. Using "mvm -X package" yields the following error:
[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.

org.osgi.framework.ServiceRegistration does not take parameters
Based on a previous question, an OSGI blogpost explains that the problem was fixed in a later (4.3.1) version of the library.
I tried to refer a newer version of this library in the POM.xml file:
<dependency>
<groupId>org.osgi</groupId>
<artifactId>core</artifactId>
<version>6.0.0</version>
<scope>system</scope>
<systemPath>/c:/Users/user/Downloads/osgi.core-6.0.0.jar</systemPath>
</dependency>
and even downloaded the newer version to specifically target it.
The error still occurs. Is there any way to solve it?
EDIT:
Attempting the solution suggested by @Balazs Zsoldos didn't help and I received the same error message. I noted an import of this package (org.osgi.framework) referring version 1:
<Bundle-Activator>org.protege.owl.server.Activator</Bundle-Activator>
<Bundle-SymbolicName>org.protege.owl.server</Bundle-SymbolicName>
<Bundle-Vendor>The Protege Development Team</Bundle-Vendor>
<Embed-Dependency>antlr, antlr-runtime, stringtemplate</Embed-Dependency>
<Export-Package>org.protege.owl.server*;version=2.0.6-SNAPSHOT</Export-Package>
<Import-Package>!org.antlr.stringtemplate,
!org.apache.commons.cli,
org.osgi.framework;version="1",
*</Import-Package>
An attempt to remove this line did not help either, as it appears in another dependency down stream. I could not find out how to override the downstream import-package instruction.
The effective pom.xml, as generated by eclipse, is attached as a link: https://docs.google.com/document/d/1eHFalUHVZ45ejLes_eqaXLw6ttjcTryphbGr_CKbhRk/edit?usp=sharing
The issue is that older versions of osgi.core are still on the classpath of the as they are imported with different group and artifact ids. Drag and drop the pom.xml to your eclipse and see the Dependency Hierarchy tab of the pom editor to get more information.
The following two are imported by dependencies:
To solve the problem, you should add the following dependency:
<dependency>
<groupId>org.osgi</groupId>
<artifactId>org.osgi.core</artifactId>
<version>6.0.0</version>
<scope>provided</scope>
</dependency>
And as this does not override the org.apache.felix:org.osgi.core dependency, exclude that one:
<dependency>
<groupId>net.sourceforge.owlapi</groupId>
<artifactId>owlapi-distribution</artifactId>
<version>3.4.5</version>
<exclusions>
<exclusion>
<groupId>org.apache.felix</groupId>
<artifactId>org.osgi.core</artifactId>
</exclusion>
</exclusions>
</dependency>
(and remove the dependency with system scope as you do not need it and its artifactId is different from the standard anyway).
Edit
Just realized that the old osgi.core package is also inside org.apache.felix:org.apache.felix.framework that is pulled transitively by ProtegeLauncher via org.apache.felix:org.apache.felix.main:4.0.3. This means that you should either
I tried the second one and another issue comes that surfire plugin cannot be downloaded from maven central (or something similar, you will see).
Notes
The developer of this protege library was clearly not familiar how maven dependency management works and what should have been imported as a dependency. The project imports an OSGi runtime environment transitively that should never happen. For compilation only API should be imported and if the target runtime surely contains that API, it should be imported with provided scope. I would recommend to
