Hibernate version:
3.1 rc2 and 3.0.5

I'm using the schemaexport ant task to build database ddl from my *.hbm.xml files. When I run my ant build I get the following error from the schemaexport task

Schema text failed: component class not found: com.mycomp.domain.ItemPK

my schemaexport target in my build file looks like

<taskdef name="schemaexport"
classname="org.hibernate.tool.hbm2ddl.SchemaExportTask">
<classpath refid="project.classpath" />
</taskdef>

<target name="generate.ddl" depends="generate.hibernate.hbm">
<schemaexport quiet="no" text="yes" drop="no" delimiter=";"
output="${distribute_dir}/ai.ddl">
<fileset dir="build">
<include name="**//domain/*.hbm.xml" />
</fileset>
</schemaexport>
</target>


the output when running the target looks like this

generate.ddl:
[schemaexport] (cfg.Environment 474 ) Hibernate 3.1 rc2
[schemaexport] (cfg.Environment 504 ) hibernate.properties not found
[schemaexport] (cfg.Environment 520 ) using CGLIB reflection optimizer
[schemaexport] (cfg.Environment 550 ) using JDK 1.4 java.sql.Timestamp handling
[schemaexport] (cfg.Configuration 233 ) Reading mappings from file: /myfiles/com/mycomp/domain/ItemTag.hbm.xml
[schemaexport] (cfg.HbmBinder 266 ) Mapping class: com.mycomp.domain.ItemTag -> ITEMMGR.ITEM_TAG
[schemaexport] (cfg.Configuration 1027) processing association property references
[schemaexport] (cfg.Configuration 1049) processing foreign key constraints

BUILD FAILED
/build.xml:58: Schema text failed: component class not found: com.mycomp.domain.ItemTagPK


There are more tables but I removed them to simplify the output. The funny thing is if I run the target again without rebuilding my java objects(ItemTag and ItemTagPK) everything works fine and the ddl is produced. The error only happens when schemaexport is run on the same pass as my java code was compiled.

I get the same "two pass" behavior when I use hibernate 3.0.5 but I get this additional error message from the schemaexport task

[schemaexport] (cfg.HbmBinder 422 ) Could not perform validation checks for component as the class com.mycomp.domain.ItemTagPK was not found

Has anyone seen this? Anyone have advice?

Thanks in Advance

possibly because the classpath used by schemaexport does not contain the class yet

I tried several things to get the compiled classes onto the classpath but I had little luck. I ended up downloading the hibernate-tools jar and switched to the hibernatetool/hbm2ddl task. This worked so I decided to use it instead of schemaexport.

Thanks

yes - the hibernate tools hbm2ddl task has better classloading.

uses the same schemaexport though, so no loss ;)
