ODK Developers,
We're having trouble building the new Aggregate v1.3. The trouble stems
from the following build error:
[INFO] Loading inherited module 'org.opendatakit.aggregate.AggregateUI'
[INFO] Loading inherited module 'com.google.gwt.maps.Maps'
[INFO] Loading inherited module 'com.google.gwt.jsio.JSIO'
[INFO] [ERROR] Unexpected error while processing XML
[INFO] java.lang.UnsupportedClassVersionError:
com/google/gwt/jsio/rebind/JSWrapperGenerator : Unsupported major.minor
version 51.0
This seems to stem from gwt-google-maps-v3-snapshot.jar, and the error
suggests that it was built using JDK 7 (1.7) rather than 6 (1.6). We always
build with JDK 6 because the target environment is JRE 6. Though in theory
we could use JDK 7 to build for JRE 6 (since the pom.xml specifies 1.6 as
the target), we figure it's safest to just build with JDK 6. In this case,
gwt-google-maps-v3-snapshot.jar seems to have maybe been built for a 1.7
target.
Rather than shift all build environments to JDK 7 -- and possibly all
runtime environments to JRE 7 -- we figured that we would just rebuild
gwt-google-maps-v3-snapshot.jar. And sure enough, we found instructions for
rebuilding in opendatakit.components/README.txt.
Unfortunately, those instructions reference a public repo (
http://code.google.com/p/gwt-google-maps-v3/) that no longer exists and,
apparently, was deprecated long ago. Alternative repos that do exist (e.g.,
https://code.google.com/p/gwt-maps3,
https://code.google.com/p/gwt-google-apis, or
https://github.com/branflake2267) appear to differ substantially. Thus, we
cannot pull the sources with which to rebuild the necessary jar.
I see two obvious solutions. One, somebody pushes the
old gwt-google-maps-v3 sources into the opendatakit.components repo so that
we can rebuild. And/or, two, somebody rebuilds the jar for Java 6. Or..?
Thanks very much,
Chris
Yes, it took quite some time to find a good, thin, Google Maps v3 library.
The others seemed to add a lot of excess boilerplate.
I've just added my Eclipse project files for 'gwt-google-maps-v3' to the
'Aggregate Components' project.
This lacks the change history of those files, but since the original
project has vanished, that seems irrelevant?

Hi Mitch,
Thank you -- that was all I needed.
For what it's worth, I did need to change your Eclipse configuration. It
was set to use JDK 1.7 system libraries and build .class files with 1.7
compatibility. Once I changed to 1.6 libraries and compatibility, the
rebuilt .jar worked great. That then matched the Aggregate config (which is
1.6).
Thanks again,
Chris

Thanks. I'll look into revising the project to set a 1.6 JRE target.
