[feature request] Support packaging as an OSGi bundle

[Andrew-Cottrell]

I suspect the following would need to be changed/added in the POM

<project>
	<packaging>bundle</packaging>

	<build>
		<plugins>
			<plugin>
				<groupId>org.apache.felix</groupId>
				<artifactId>maven-bundle-plugin</artifactId>
				<version>4.1.0</version>
				<extensions>true</extensions>
			</plugin>
		</plugins>
	</build>
</project>

Hi,

As I do not use OSGi I'm not fully comfortable maintaining it. How does this work? Does it create a new OSGi compatible jar? Is it the same jar? Is there no easy way to wrap jars to make them OSGi compatible (outside of this project)?

[Andrew-Cottrell]

Hi patrickfav

Yes, it creates an OSGi compatible jar and it's the same jar. The jar should be exactly the same as before, other than additions to META-INF/MANIFEST.MF. It is easy to wrap jars; however, this makes them much harder to use: can't simply add the dependency to a project's pom.xml.

FYI, another BCrypt implementation does this
svenkubiak/jBCrypt@89da34b
https://github.com/svenkubiak/jBCrypt/blob/0.4.1/pom.xml
https://mvnrepository.com/artifact/de.svenkubiak/jBCrypt/0.4.1

Alright, let me look into this, if the change is transparent for anybody that does not use OSGi then thats fine for me.

[Andrew-Cottrell]

Yes, the change should be transparent for non-OSGi uses. Thanks for looking in to this.

Hi,

I've pushed the changes to this feature branch: https://github.com/patrickfav/bcrypt/tree/feat-15-osgi

Could you please checkout, in the root directory run

./mvnw clean install

to install the snapshot version into your local repo and change your dependency to

    <dependency>
        <groupId>at.favre.lib</groupId>
        <artifactId>bcrypt</artifactId>
        <version>0.8.0-SNAPSHOT</version>
    </dependency>

and give me feedback if that works? I have no osgi project to test it on (and to be frank never used it before) :)

Cheers!

Hi

Looks like at.favre.lib:bcrypt is perfect. I was able to build and install the bcrypt-feat-15-osgi modules using Maven, and then to deploy and depend upon the bcrypt module as an OSGi bundle.

Import-Package: at.favre.lib.crypto.bcrypt;version="[0.8.0,0.9.0)"

But it's only partly working as there is a dependency on at.favre.lib:bytes, which is not currently OSGi compatible. Without at.favre.lib:bytes also being an OSGi bundle it doesn't work at runtime.

Cheers!

(sorry, didn't mean to close)

Hi, I've released a new bytes version with also OSGi support. For now the support is added, but I can't guarantee it for the lifetime of this project as the requirement that every transitive dependency must ALSO be OSGi compatible makes it quite restricting.

I'm soon releasing 0.8.0 - please leave me a line to tell me if the lib now works with your project.

[patrickfav]

Released.

[Andrew-Cottrell]

BCrypt 0.8.0 (and Bytes 1.1.0) works great with my projects. Thanks for adding OSGi support.
