--------------------------------------
Summary: Unresolved repository inside the feature causes Karaf
freezing during startup
Key: KARAF-4031
URL: https://issues.apache.org/jira/browse/KARAF-4031
Project: Karaf
Issue Type: Improvement
Affects Versions: 4.0.1
Environment: Windows
Reporter: Andrei Shakirin
I have observed following behavior: there is a feature containing a repository
URL inside the feature.xml:
<code>
<?xml version="1.0" encoding="UTF-8"?>
<features
name="${project.artifactId}-${project.version}"
xmlns="http://karaf.apache.org/xmlns/features/v1.0.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://karaf.apache.org/xmlns/features/v1.0.0
http://karaf.apache.org/xmlns/features/v1.0.0 ">
<repository>mvn:org.mycompany/thirdparty-features/9.9.9/xml</repository>
<feature name="test-bad" version="${project.version}">
<feature>thirdparty-commons</feature>
</feature>
</features>
</code>
The repository URL mvn:org.mycompany/thirdparty-features/9.9.9/xml is not exist
and cannot be resolved.
I specify the feature URL in org.apache.karaf.features.cfg
featuresRepositories, but NOT mention the feature in featuresBoot:
<code>
featuresRepositories = \
mvn:org.apache.karaf.features/enterprise/4.0.1/xml/features, \
mvn:org.apache.karaf.features/framework/4.0.1/xml/features, \
mvn:org.apache.karaf.features/spring/4.0.1/xml/features, \
mvn:org.apache.karaf.features/standard/4.0.1/xml/features,\
mvn:org.mycompany/test-bad/1.0.0-SNAPSHOT/xml
#
# Comma separated list of features to install at startup
#
featuresBoot = \
aries-blueprint, \
bundle, \
config, \
deployer, \
diagnostic, \
feature, \
instance, \
jaas, \
kar, \
log, \
management, \
package, \
service, \
shell, \
shell-compat, \
ssh, \
system, \
wrap
</code>
Current behavior:
1) Karaf writes error message in the log file:
java.io.IOException: Error resolving artifact
de.conrad.ccp.basit:thirdparty-features:xml:9.9.9: Could not find artifact
de.conrad.ccp.basit:thirdparty-features:xml:9.9.9 in central
(http://repo1.maven.org/maven2/) :
mvn:de.conrad.ccp.basit/thirdparty-features/9.9.9/xml
(absolutely correct)
2) further startup process is completely blocked (problem)
Expected behavior: write error message and continue startup process: feature is
not specified in featuresBoot and must not be installed.
Interesting, if unresolved feature URL is specified directly in
featuresRepositories, Karaf proceed it correctly: writes error message, but
continues startup. Blocking appears only if unresolved URL is specified inside
the feature.xml.
