awips2/docs/dev/build-datadelivery.md

Data Delivery has been implemented into the AWIPS(II) baseline to provide access to data that is not resident locally at a Weather Forecast Office, River Forecast Center, or National Center. Data Delivery gives users the ability to create queries (One Time Requests) and subscriptions to data sets (provided OGC / OpenDAP servers such as THREDDS).

Notice the last two commented out, com.raytheon.uf.edex.datadelivery.feature and com.raytheon.uf.edex.ogc.feature. These feature sets do not exist, but could easily be created in the same wat as other features (like com.raytheon.uf.common.base.feature, com.raytheon.uf.edex.base.feature, etc.

wa-build

The source code comments provide the following guidance:

In the work assignment's edexOsgi/build.edex directory, create a file named similar to the following: edexOsgi/build.edex/5-Data_Delivery-wa-build.properties In the file, there should be one line such as: wa.features=feature1,feature2

However, the wa-build Ant target requires a file features.txt exist. So if is 5-Data_Delivery-wa-build.properties or features.txt? Because the delimiter being specified is a line separator (and not a comma "wa.features=feature1,feature2" as with versions proir to 16.2.2).

So we can infer that a file should exist called features.txt should exist which has one WA feature per line. And what do you know, a similar file exist for the CAVE build in awips2-builds/cave/build/features.txt:

cat awips2-builds/cave/build/features.txt
com.raytheon.uf.common.base.feature
com.raytheon.uf.viz.dataplugin.obs.feature
...
