Summary: OSGI: Self-imported package causes failure upon Karaf restart
Key: IGNITE-11668
URL:
https://issues.apache.org/jira/browse/IGNITE-11668 Project: Ignite
Issue Type: Bug
Components: osgi
Affects Versions: 2.7
Reporter: Oleksii Mohylin
I've got problem using Ignite 2.7 in Apache Karaf 4.2.0. The problem is caused by strange bundle meta of ignite-osgi. It exports package org.apache.ignite.osgi.classloaders and imports it at the same time. Here's extract from METADATA.MF:
{noformat}
Import-Package: org.apache.ignite;version="[2.7,3)",org.apache.ignite.
configuration;version="[2.7,3)",org.apache.ignite.internal.util;versi
on="[2.7,3)",org.apache.ignite.internal.util.tostring;version="[2.7,3
)",org.apache.ignite.internal.util.typedef.internal;version="[2.7,3)"
,org.apache.ignite.osgi.classloaders,org.osgi.framework;version="[1.7
,2)"
Require-Capability: osgi.ee;filter:="(&(osgi.ee=JavaSE)(version=1.8))"
Fragment-Host: org.apache.ignite.ignite-core
Export-Package: org.apache.ignite.osgi.classloaders;uses:="org.apache.
ignite.internal.util.tostring,org.osgi.framework";version="2.7.0",org
.apache.ignite.osgi;uses:="org.apache.ignite,org.apache.ignite.config
uration,org.apache.ignite.osgi.classloaders,org.osgi.framework";versi
on="2.7.0"
{noformat}
There is no problem with initial installation of my application into Karaf, although after Karaf ignite-osgi dependency is not resolved, and this exception in log:
{noformat}
org.osgi.framework.BundleException: Unable to resolve graphql-core [399](R 399.0): missing requirement [graphql-core [399](R 399.0)] osgi.wiring.package; (&(osgi.wiring.package=org.apache.ignite.osgi.classloaders)(version>=2.7.0)(!(version>=3.0.0))) [caused by: Unable to resolve org.apache.ignite.ignite-osgi [432](R 432.0): missing requirement [org.apache.ignite.ignite-osgi [432](R 432.0)] osgi.wiring.host; (&(osgi.wiring.host=org.apache.ignite.ignite-core)(bundle-version>=0.0.0))] Unresolved requirements: [[graphql-core [399](R 399.0)] osgi.wiring.package; (&(osgi.wiring.package=org.apache.ignite.osgi.classloaders)(version>=2.7.0)(!(version>=3.0.0)))]

*Proposed solution:*
remove the self-import by adding instruction to bundle plugin configuration in modules/osgi/pom.xml
{code:java}
<plugin>
<groupId>org.apache.felix</groupId>
<artifactId>maven-bundle-plugin</artifactId>
<configuration>
<instructions>
<Fragment-Host>org.apache.ignite.ignite-core</Fragment-Host>
<Import-Package>!org.apache.ignite.osgi.classloaders,*</Import-Package>
</instructions>
</configuration>
</plugin>
