Greetings, |
| 5 |
|
| 6 |
Currently, 'dojar' is a script part of each sys-apps/portage release. I am |
| 7 |
proposing to deprecate all Java ebuild functions from Portage and move |
| 8 |
them into the Java eclass. |
| 9 |
|
| 10 |
In terms of what this means: |
| 11 |
|
| 12 |
1. It's easier to implement new functions in an eclass. |
| 13 |
2. We can roll out new functions faster instead of waiting for them to get |
| 14 |
checked into Portage and go through Portage's qa cycle. |
| 15 |
3. dojar would be immediately enhanced to allow more control over how |
| 16 |
CLASSPATH gets set in package.env. |
| 17 |
|
| 18 |
I would take initial responsibility for bumping all ebuilds that currently |
| 19 |
use 'dojar' to use the new eclass when it's ready. Currently only (6) |
| 20 |
ebuilds outside of dev-java use 'dojar': portagemaster, postgresql, |
| 21 |
jboss, orion, tomcat, pdflib. |
| 22 |
|
| 23 |
dojar would be replaced with java_dojar(). |
| 24 |
|
| 25 |
My initial plans for enhancing jar file installation will be for |
| 26 |
correctness in /usr/share/${PN}/package.env. I will be giving ebuilds the |
| 27 |
chance to prepend and/or append to the CLASSPATH setting. (Order |
| 28 |
sometimes matters.) |
| 29 |
|
| 30 |
For example, see bug #10360. To solve this bug, I would add the following |
| 31 |
to the ant ebuild: |
| 32 |
|
| 33 |
JAVA_DEP_PREPEND="junit" |
| 34 |
|
| 35 |
Multiple packages (space separated) could be supplied here. The packages |
| 36 |
can be whatever the developer wants, providing that the package(s) |
| 37 |
indicated exist and have a package.env. Additionally, there is |
| 38 |
JAVA_DEP_APPEND if one wants some dependencies at the _end_ of the |
| 39 |
CLASSPATH. In this case, it doesn't matter whether junit gets prepended |
| 40 |
or appended, as long as it ends up in the CLASSPATH. |
| 41 |
|
| 42 |
What happens next? In the example of #10360, the java eclass would in turn |
| 43 |
process that variable by reading junit's package.env, get the CLASSPATH |
| 44 |
and prepend that to the CLASSPATH it is writing for ant's package.env. |
| 45 |
|
| 46 |
This would close the bug and would also solve a lot of other similar bugs |
| 47 |
down the line. |
| 48 |
|
| 49 |
Comments? Flames? Agreements? |
