General Discussion

Hi there,

I am using the liquibase plugin and I keep getting the following error:

  1. [ERROR] Failed to execute goal org.liquibase:liquibase-maven-plugin:2.0.3:update (default) on project dbmigration: Error setting up or running Liquibase: java.lang.RuntimeException: Cannot find database driver: org.postgresql.Driver -> [Help 1]
  2. org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.liquibase:liquibase-maven-plugin:2.0.3:update (default) on project dbmigration: Error setting up or running Liquibase: java.lang.RuntimeException: Cannot find database driver: org.postgresql.Driver



I am configuring the liquibase plugin as follows:


  2.                
  3.                        
  4.                                 org.apache.maven.plugins
  5.                                 maven-compiler-plugin
  6.                                 2.3.2
  7.                                
  8.                                         1.6
  9.                                         1.6
  10.                                
  11.                        
  12.                        
  13.                                 org.liquibase
  14.                                 liquibase-maven-plugin
  15.                                 2.0.3
  16.                                
  17.                                        
  18.                                                 process-resources
  19.                                                
  20.                                                         update
  21.                                                
  22.                                        
  23.                                
  24.                                
  25.                                        
  26.                                                 postgresql
  27.                                                 postgresql
  28.                                                 9.0-801.jdbc4
  29.                                        
  30.                                
  31.                                
  32.                                         db/changelog-master.xml
  33.                                         org.postgresql.Driver
  34.                                         myurl
  35.                                         user
  36.                                         pass
  37.                                         false
  38.                                         main
  39.                                
  40.                        
  41.                
  42.            


and the following dependency is part of my project:



  1.        
  2.                
  3.                         postgresql
  4.                         postgresql
  5.                         9.0-801.jdbc4
  6.                         jar
  7.                         compile
  8.                
  9.        



If I manually inspect the specified postgres jar, it does contain the class org.postgresql.Driver.

And if I run maven with debugging output turned on, it looks like the plugin’s classpath contains that jar:


  1. [DEBUG] Created new class realm plugin>org.liquibase:liquibase-maven-plugin:2.0.3
  2. [DEBUG] Importing foreign packages into class realm plugin>org.liquibase:liquibase-maven-plugin:2.0.3

Any help is very much appreciated!
