Maven: PL/SQL script with sql-maven-plugin throws error PLS-00103

Question

I'm trying to use the sql-maven-plugin to execute a PL/SQL script on an Oracle 11 database. Although the script is valid PL/SQL (as far as I can tell), the execution gives me a PLS-00103 error:

The SQL script: (drop_all_tables.sql)

BEGIN
   EXECUTE IMMEDIATE 'DROP TABLE MY_TABLE';
   EXCEPTION
   WHEN OTHERS THEN
      IF SQLCODE != -942 THEN
         RAISE;
      END IF;
END;

And my plugin configuration:

<plugin>
            <groupId>org.codehaus.mojo</groupId>
            <artifactId>sql-maven-plugin</artifactId>
            <version>1.5</version>

            <dependencies>
                <dependency>
                    <groupId>oracle</groupId>
                    <artifactId>jdbc</artifactId>
                    <version>11.2.0.2.0</version>
                </dependency>
            </dependencies>
            <executions>
                <execution>
                    <id>create-schema</id>
                    <phase>process-test-resources</phase>
                    <goals>
                        <goal>execute</goal>
                    </goals>
                    <configuration>
                        <driver>oracle.jdbc.driver.OracleDriver</driver>
                        <url>${jdbc.url}</url>
                        <username>${jdbc.username}</username>
                        <password>${jdbc.password}</password>
                        <autocommit>true</autocommit>
                        <srcFiles>
                            <srcFile>src/main/resources/sql/drop_all_tables.sql</srcFile>
                        </srcFiles>
                    </configuration>
                </execution>
            </executions>
        </plugin>

And this is the output from the Maven execution:

[ERROR] Failed to execute:  BEGIN
EXECUTE IMMEDIATE 'DROP TABLE MY_TABLE';
[INFO] ------------------------------------------------------------------------
[ERROR] BUILD ERROR
[INFO] ------------------------------------------------------------------------
[INFO] ORA-06550: line 2, column 43:

   insert open rollback savepoint set sql execute commit forall
   merge pipe purge

Answer 1

I guess the plugin is splitting the sql script by semicolons and trying to execute each part independently. The first statement would be

BEGIN
    EXECUTE IMMEDIATE 'DROP TABLE MY_TABLE';

Which is incomplete as far as oracle is concerned. The plugin does have two configuration parameters to change this behaviour, delimiter and delimiterType. By changing the configuration like below and separating your BEGIN blocks by a / on a line by itself you should be able to execute this script.

<configuration>
    <delimiter>/</delimiter>
    <delimiterType>row</delimiterType>
</configuration>
