Re: [Dev][lo4j2] Could not find a logging implementation in osgi bundle.

[Chathura Priyankara]

Hi,

Currently I'm using single osgi bundler for all following dependencies.

     <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-api</artifactId>
        <version>2.2</version>
    </dependency>
    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-core</artifactId>
        <version>2.2</version>
    </dependency>
      <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-jcl</artifactId>
        <version>2.2</version>
    </dependency>
    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-1.2-api</artifactId>
            <version>2.2</version>
    </dependency>
    <dependency>
        <groupId>org.apache.logging.log4j</groupId>
        <artifactId>log4j-slf4j-impl</artifactId>
        <version>2.2</version>
    </dependency>

and use packages as follows

  <Import-Package>
          !org.apache.log4j.*,
           *;resolution:=optional
  </Import-Package>
   <Export-Package>
           org.apache.logging.log4j.*;version="${version.log4j}",
           org.apache.logging.log4j.core.*;version="${version.log4j}",
           org.apache.logging.slf4j.*;version="${version.log4j}",
           org.slf4j.impl.*;version="${version.log4j}",
          org.apache.log4j.*;version="${version.log4j}"
  </Export-Package>

Do I need to create separate bundles for all these packages ?

Thanks!
