org.apache.sling.api.resource,version=[2.3,3) -- 无法解析

Question

Hi I am not able to access content of my project, I have uploaded all the packages which are required to access content from CQ. Only thing I can see is

org.apache.sling.api.resource,version=[2.3,3) -- Cannot be resolved

Can this be the reason for exception and if yes please let me know how to resolve it.

CQ version 5.6

Answer 1

The error message means that the OSGi framework is unable to supply a version >= 2.3 and < 3 of the org.apache.sling.api.resource Java package for a bundle B that wants to import it.

As a result, bundle B cannot be activated, and parts of your system won't work.

Looking at the webconsole (under /system/console by default in Sling and CQ) you can see that this package is provided by the org.apache.sling.api bundle , so either you have an old version of that bundle in your system, or you have installed incompatible bundles that require a newer version of that package.

Answer 2

You can add the missing package by explicilty importring it. Accecess the pom.xml file in the core folder of your project core/pom.xml and list the dependency under Import-Package

<configuration>
    <bnd><![CDATA[
        Import-Package: 
            javax.annotation;version=0.0.0,
            org.apache.sling.api.servlets;version="[2.3,3)",*
     ]]></bnd>
</configuration>

Answer 3

Check version of org.apache.sling.api.resource in package-info.class file in org.apache.sling.api.resource package in uber-jar.

You might have version between 2.3 and 3. Try installing lower version uber-jar that has package version <2.3
