Ate Douma updated JS2-1025:
---------------------------
Priority: Minor (was: Major)
The problem really is with MySQL, this is not a Jetspeed bug.
The unique index cannot be made shorter without a complete object remodelling,
we need all these columns in the index as it represent a *logical* model
constraints.
The fact you're overrunning the *mysql* limit of 1000 bytes key length
indicates you most likely are using an extremely long preference name.
I suggest trying to reduce your preference name length as easiest solution here.
> Mysql maven2 build error - UNIQUE INDEX key too long

> Key: JS2-1025
> URL: https://issues.apache.org/jira/browse/JS2-1025
> Project: Jetspeed 2
> Issue Type: Bug
> Components: Project Build
> Affects Versions: 2.2.2
> Environment: WinXP, jdk 1.6, mysql 5.0.45 community-nt
> Reporter: Evangelos Vlachogiannis
> Priority: Minor

> While building a custom j2.2 portal I got the following error:
> Embedded error: Failed to execute: CREATE UNIQUE INDEX
> UIX_PORTLET_PREFERENCE
> ON PORTLET_PREFERENCE (DTYPE, APPLICATION_NAME, PORTLET_NAME, ENTITY_ID,
> USER_NA
> ME, NAME)
> Specified key was too long; max key length is 1000 bytes
> [INFO]
> ------------------------------------------------------------------------
> [INFO] Trace
> org.apache.maven.lifecycle.LifecycleExecutionException: Unexpected error
> I think that the:
> CREATE UNIQUE INDEX UIX_PORTLET_PREFERENCE ON
> PORTLET_PREFERENCE (DTYPE, APPLICATION_NAME, PORTLET_NAME, ENTITY_ID,
> USER_NAME, NAME)
> query needs to be replaced with a shorter index e.g. (DTYPE,
> APPLICATION_NAME, PORTLET_NAME) but I do not know about side effects.
> Please provide fix and deploy also to jars as people cannot build custom
> portals with j2.2 / mysql
