openjpaEnhance task failing during build

[andrew-sumner]

I get the following error when building via gradle. Any ideas why the openjpaEnhance would throw this error?

Removing apply plugin: 'openjpa' fxies the failure but dosen't apply the enahncement.

It seems, your meta-model-build requires servlet-api in the classpath Try to add classpath 'javax.servlet:servlet-api:2.5' to your dependencies

[andrew-sumner]

It made no difference and as I later discovered it wasn't required as I have another dependancy which already includes it.

Here's the relevant portion of the stacktrace incase that helps

the plugin does not pick up "providedCompile"-dependencies only those in the 'compile'-configuration https://github.com/schmutterer/gradle-openjpa/blob/64fa9f7ea5f0b2704e6be637d5c7af05ca5685d2/src/main/groovy/at/schmutterer/oss/gradle/openjpa/OpenJpaPlugin.groovy#L49

I have getting this error:

• What went wrong: A problem occurred evaluating root project 'xyz'.

  Cannot get property '*/exception/' on null object

when have this:

apply plugin: 'openjpa' openjpa { excludes ['*/exception/'] }

@robert-nemet , I think issue #3 handles your problem.

[ChristophGr]

Alright, I'll close this one, and we continue in #3
