Deploy Gitbucket on Wildfly

When trying to deploy the Gitbucket project into wildfly I go tthe following error message:

WARN [org.jboss.modules] (ServerService Thread Pool -- 81) Failed to define class liquibase.serializer.core.yaml.YamlSerializer$LiquibaseRepresenter in Module "deployment.gitbucket.war:main" from Service Module Loader: java.lang.NoClassDefFoundError: Failed to link liquibase/serializer/core/yaml/YamlSerializer$LiquibaseRepresenter (Module "deployment.gitbucket.war:main" from Service Module Loader): org/yaml/snakeyaml/representer/Representer ...

This is a known issue and discussed here.

You can fix it if you add the file ‘jboss-deployment-structure.xml’ into the WEB-INF/ folder with the following content:

<jboss-deployment-structure>
  <deployment>
    <dependencies>
      <system export="true">
        <paths>
          <path name="com/sun/net/ssl/internal/ssl" />
          <path name="com/sun/net/ssl" />
        </paths>
      </system>
      <!-- add snakeyaml dependency -->
      <module name="org.yaml.snakeyaml"/>
    </dependencies>
  </deployment>
</jboss-deployment-structure>

How to install:

The following is a short install guide how to modify the gitbucket.war downloaded form the project release page:

1.) Download latest version from release page:

wget https://github.com/gitbucket/gitbucket/releases/download/4.7.1/gitbucket.war

change the version if needed

2.) unzip the war file

unzip gitbucket.war -d tmp/gitbucket.war

3.) create the ‘jboss-deployment-structure.xml’ file and add the content as explained above. Than copy the file into the WEB-INF folder

cp jboss-deployment-structure.xml /tmp/gitbucket.war/WEB-INF/

4.) create the doDeploy file

touch tmp/gitbucket.war/gitbucket.war.dodeploy

5.) start deployment by moving the folder to the wildfly deploy directory

cd tmp/
mv gitbucket.war /opt/wildfly/standalone/deployments/

Install Script

You can use also my install script from here to install gitbucket on Wildfly 9.x & 10.x under Linux.

/bin/bash wildfly-install.sh [INSTALLDIR] [GITBUCKET-VERSION]

You can specify the install directory of your wilfly installation and the gitbucket version.

Example:

/bin/bash wildfly-install.sh [INSTALLDIR] [GITBUCKET-VERSION]

Note: The script must be run as root. The script assumes that wildfly is running with the user ‘wildfly’. You can change this in your script if needed.
