Just a minor modification: in M2 you can also include the optional
dependencies in the <dependencies> section, but each of them must
contain the tag <optional>true</optional>.
For example:
<dependency>
<groupId>visad</groupId>
<artifactId>visadNoDods</artifactId>
<version>1.2.3</version>
<optional>true</optional>
</dependency>

Is it easy to host our own jar files, or do you need to use

The current maven design uses ibiblio.org as a starting point, so while
it's technically possible to host elsewhere, the nett effect of doing this
means people will assume the jar is not available.
That sounds great. One question, how does versioning work around
dependencies? For example, version 2.2.17 has somewhat different
dependencies than 2.2.16.
Each published jar defines both the name and version of each of it's
dependencies in a "project object model" file. Should an end user indicate
to maven that they want to use v2.2.17 instead of v2.2.16, maven downloads
the new pom file, sees new dependencies are being used, and downloads
those new dependencies automatically.
ok, heres the scoop for version 2.2.16
We create the following jar files:
ncCore-2.2.16.jar just the core netcdf-java classes
netcdf-2.2.16.jar complete netcdf-java, except for the UI and
optional libraries
netcdfUI-2.2.16.jar complete netcdf-java including the UI, without
optional libraries
toolsUI-2.2.16.jar complete netcdf-java including the UI and
optional libraries
nc2.2.jar library that can be used in the IDV
The optional libraries:
bufr.jar required to read Bufr datasets
commons-httpclient required to read files remotely over HTTP
commons-logging, codec required by commons-httpclient
gnu-regexp required by dods; dods library itself is now
directly contained in netcdf
grib.jar required to read Grib-1 or Grib-2 datasets
jdom.jar required to read thredds catalogs, and read
NcML
jpeg2000.jar required to read Grib-2 JPEG2000 compressed
files
nlog4j.jar log4j logging. Alternately, you can use any
slf4j implementation.
visadNoDods.jar required to read ADDE datasets; this version
has the dods libraries removed
xercesImpl.jar required to validate thredds catalogs (jdk
1.4 only)
xml-apis.jar required by xerces library
prefsAll.jar required for UI state persistence, related
widgets
resourcesOptional.jar optional detailed maps and tables
The dependencies are somewhat complicated by that fast that you can
leave out the optional libraries if you dont need the feature. In what
follows I will assume you want all the optional features. So a
dependency graph would be:
jar
library depends on
ncCore-2.2.16.jar none
netcdf-2.2.16.jar bufr, commons-httpclient, gnu-regexp, grib.jar,
jdom.jar, visadNoDods.jar, xercesImpl.jar (jdk1.4 only)
netcdfUI-2.2.16.jar same as netcdf-2.2.16.jar, plus prefsAll.jar,
resourcesOptional.jar
toolsUI-2.2.16.jar none, its all in one big jar
nc2.2.jar none other than whats already in the IDV
grib.jar jpeg2000.jar
xercesImpl.jar xml-apis.jar
commons-httpclient commons-logging, commons-codec
The project I am working on uses the netcdf v2.1 jar file - do you have
the dependancy tree of the files in the v2.1 tree?
The full recipe for publishing to www.ibiblio.org is here:
http://maven.apache.org/guides/mini/guide-ibiblio-upload.html
Essentially, you submit your released packaged jar along with a pom.xml
file, which for ncCore-2.2.16 might look like this:
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>edu.ucar</groupId>
<artifactId>ncCore</artifactId>
<version>2.2.16</version>
<packaging>jar</packaging>
<name>Core netcdf-java classes</name>
<url>http://www.unidata.ucar.edu/software/netcdf-java/</url>

And for netcdf-2.2.16 might look like this:
<project>
<modelVersion>4.0.0</modelVersion>
<groupId>edu.ucar</groupId>
<artifactId>netcdf</artifactId>
<version>2.2.16</version>

Is the visad project also a ucar.edu project?
