Assignee: Jerome Lacoste

>
> Key: MEXEC-10
> URL: http://jira.codehaus.org/browse/MEXEC-10
> Project: Mojo Exec Plugin
> Issue Type: Bug
> Affects Versions: 1.0.1
> Reporter: Jerome Lacoste
> Assigned To: Jerome Lacoste
> Priority: Critical
> Fix For: 1.0.2
>
>
> Reported by "BEHRING Carsten"
> Dear Jerome,
>
> as I did not find an other way to report a bug for the
> exec-maven-plugin, allow me to do it via email.
>
> I use the exec-maven-plugin to run a little program that uses hibernate
> for database access.
>
> I want to pass parameters via systemProperties and configure the plugin
> like this:
>
>
> <plugin>
> <groupId>org.codehaus.mojo</groupId>
> <artifactId>exec-maven-plugin</artifactId>
> <executions>
> <execution>
> <goals>
> <goal>java</goal>
> </goals>
> </execution>
> </executions>
> <configuration>
> <systemProperties>
> ....
> </property>
> <key>ds.password</key>
> <value></value>
> </property>
> </systemProperties>
> </configuration>
> </plugin>
>
> The "ds.password" value needs to be "empty string". If I run it this way
> I get an NPE:
>
> java.lang.NullPointerException
