----------------------------------
Summary: Error "No karaf base dir found in extracted
distribution." when using customized Karaf distribution
Key: KARAF-2388
URL: https://issues.apache.org/jira/browse/KARAF-2388
Project: Karaf
Issue Type: Bug
Components: karaf-exam
Affects Versions: 3.0.0.RC1, 2.3.2
Reporter: Lukas Roedl
Following the manual at
http://karaf.apache.org/manual/latest-2.3.x/developers-guide/writing-tests.html#KarafDistributionConfigurationOption
I tried to write integration tests based on a custom Karaf distribution.
I used the following to configure the container:
{code:java}
...
karafDistributionConfiguration()
.frameworkUrl(
maven()
.groupId("at.ac.ait.hbs.homer")
.artifactId("at.ac.ait.hbs.homer.core.distribution.assemblies.stable")
.type("zip")
.versionAsInProject()
)
.karafVersion(KARAF_VERSION)
.name("Apache Karaf")
.unpackDirectory(new File(UNPACK_DIRECTORY)),
...
{code}
When running the tests I get an "No karaf base dir found in extracted
distribution." error. When looking into the "target\exam\<random>\" folder (=
UNPACK_DIRECTORY) there is really a mess:
{code}
DISCLAIMER.txt
LICENSE.txt
README.txt
...
bin\
...
config.properties
custom.properties
endorsed\
ext\
...
karaf.bat
karaf.jar
keys.properties
org\
...
system.properties
tmp\
users.properties
{code}
What I expected was the default Karaf distribution layout:
{code}
bin\
data\
demo\
deploy\
etc\
lib\
system\
README
karaf-manual-2.3.2.html
karaf-manual-2.3.2.pdf
...
{code}
Digging into the problem I found out that the eg. the apache-karaf-2.3.2.zip
looks like:
{code}
apache-karaf-2.3.2\bin\
apache-karaf-2.3.2\data\
apache-karaf-2.3.2\demo\
apache-karaf-2.3.2\deploy\
apache-karaf-2.3.2\etc\
apache-karaf-2.3.2\lib\
apache-karaf-2.3.2\system\
apache-karaf-2.3.2\README
apache-karaf-2.3.2\karaf-manual-2.3.2.html
apache-karaf-2.3.2\karaf-manual-2.3.2.pdf
...
{code}
Whereas the custom distribution I'm using looks like:
{code}
bin\
data\
demo\
deploy\
etc\
lib\
system\
README
karaf-manual-2.3.2.html
karaf-manual-2.3.2.pdf
...
{code}
Not the different "base" directory in the two packages - "apache-karaf-2.3.2"
in case of the Karaf 2.3.2 assembly.
It seems that the container assumes that every zip/tar.gz file given has this
"base" directory structure and extracts only the contents of subfolders to the
unpack directory.
I think a check for this "base" directory should be integrated in the container
and either extract only the contents in this "base" directory or extract the
whole file otherwise - the base directory seems to have the same name as the
artifact name?!
