Hi,
I've got a fairly complex project, consisting of a couple of dozen modules
all up. What I'm finding is that certain combinations of these modules don't
build together, and I think it's because of dependencies in plugins.
Case in point: the application as a whole talks to two different databases -
a MySQL database and an Oracle database. Each database has a schema module,
which is responsible for creating tables, inserting data, and so on. If I
try to build a profile that contains both modules, I get an error.
The schema POMs look like this:
Oracle POM:
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>net.twasink</groupId>
<artifactId>oracle-schema</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>
<name>Oracle Schema</name>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>sql-maven-plugin</artifactId>
<dependencies>
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc</artifactId>
<version>14</version>
</dependency>
</dependencies>
<configuration>
<delimiter>/</delimiter>
<autocommit>true</autocommit>
<driver>${database.driver}</driver>
<url>${database.test.url}</url>
</configuration>
<executions>
...
</executions>
</plugin>
</plugins>
</project>
MySQL Pom:
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>net.twasink</groupId>
<artifactId>mysql-schema</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>
<name>MySQL Schema</name>
<build>
<plugins>
<plugin>
<groupId>org.codehaus.mojo</groupId>
<artifactId>sql-maven-plugin</artifactId>
<dependencies>
<dependency>
<groupId>com.mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<version>5.0.5</version>
</dependency>
</dependencies>
<configuration>
<delimiter>/</delimiter>
<autocommit>true</autocommit>
<driver>${database.driver}</driver>
<url>${database.test.url}</url>
</configuration>
<executions>
...
</executions>
</plugin>
</plugins>
</build>
</project>
Master POM:
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>net.twasink</groupId>
<artifactId>db-schema</artifactId>
<version>1.0-SNAPSHOT</version>
<packaging>pom</packaging>
<name>Database Schemas</name>
<modules>
<module>oracle-schema</module>
<module>mysql-schema</module>
</modules>
</project>
When I try to run this sort of combination, I get this error:
<lots of log output, indicating the successful build of the Oracle schema>

Nor is this limited to the SQL plugin - I've seen similar behaviour with the
Antrun plugin. It looks like the first time a plugin is encountered, the
dependencies for that plugin are set, and subsequent configurations are
ignored. Is this behaviour intentional, or a bug?
(I've tried this with Maven 2.0.5 and 2.0.6, BTW - same symptoms)
Thanks for any help. :)
