Here’s the structure of the Jakarta Mail workspace, showing the different maven modules I needed to create to allow Jakarta Mail to be built by maven.
First, the main maven module.
pom.xml
Then, some files left over from the ant build. These are no longer used or maintained.
ant-common.xml
build.properties
build.xml
mbox.xml
project.properties
project.xml
Finally, some files for checking that the API signatures match the spec (not yet integrated into the build).
mail.sig
siggen
sigtest
The main Jakarta Mail source code module, containing all the code that goes into mail.jar.

Several modules containing demo source code. They’re buildable to make sure they do build before shipping them, but they’re shipped only as source code. Note the embedded README.txt files

Several modules that extract subsets of the mail.jar file to build other jar files. The source code for each of these jar files could be moved into these modules, and then mail.jar could be constructed by combining all these jar files. I did it this way because I like having all the source code in one place, but it’s probably less maven-like.
mailapi/pom.xml
imap/pom.xml
imap/src/main/resources/META-INF/MANIFEST.MF
imap/src/main/resources/META-INF/javamail.providers
pop3/pom.xml

smtp/pom.xml
smtp/src/main/resources/META-INF/MANIFEST.MF
smtp/src/main/resources/META-INF/javamail.address.map
smtp/src/main/resources/META-INF/javamail.providers
mailhandler/pom.xml
A module to act as parent of the imap, pop3, and smtp modules to allow sharing of some common rules.
parent-distrib/pom.xml
A module that contains only the Delivery Status Notification support. I moved all the source code here because none of this appears in mail.jar.
dsn/pom.xml
dsn/src/main/java/com/sun/mail/dsn/DeliveryStatus.java
dsn/src/main/java/com/sun/mail/dsn/MessageHeaders.java
dsn/src/main/java/com/sun/mail/dsn/MultipartReport.java

dsn/src/main/java/com/sun/mail/dsn/text_rfc822headers.java
dsn/src/main/resources/META-INF/MANIFEST.MF
dsn/src/main/resources/META-INF/mailcap
The mbox protocol provider module. Again, source code moved here because none of this appears in mail.jar. Also includes a submodule to build the native code (even though the native source code is in the upper module; is that too weird?)
mbox/pom.xml
mbox/src/main/cpp/com/sun/mail/mbox/UNIXFile.c
mbox/src/main/cpp/com/sun/mail/mbox/UNIXInbox.c

mbox/src/main/resources/META-INF/MANIFEST.MF
mbox/src/main/resources/META-INF/javamail.providers
mbox/native/pom.xml
A module just for building the javadocs. Putting these rules in the parent pom.xml just didn’t work so I moved them here.
javadoc/pom.xml
Finally, the documentation. Not a module. Most of it is copied to the website gh-pages branch when a release is published.
