eclipse plugin deployment troubleshooting [message #1071]

Hi

I have a plugin that works from the PDE environment, but when I export
it and deploy it elsewhere, it doesn't work (it has an editor with a
configured extension; it also contributes to the preference page).

I use eclipse 3.4M5 .

Is there a systematic way of debugging this case ?

Jean-Marc,

I haven't tried this in the 3.4 milestones but in 3.3 you could do the
following:

1) Start Eclipse like the following: eclipse.exe -console
2) Type "ss" in the console to get the 'short status' of all the bundles
starting up
3) Find your plugin in the list and note its bundle number
4) Type "diag <bundle-number>" in the console to see what prerequisites (if
any) are preventing your plugin from starting up.
5) If any plugins are listed that are already in the install, use "diag" to
find out what's preventing them from starting up.

HTH,
Todd

Thanks a lot!
Under the console, "diag" didn't show the problem, but "start" did:

Missing Constraint: Bundle-RequiredExecutionEnvironment: JavaSE-1.6

The problem was that I compiled in a Java 6 environment, but deployed on
Debian with only Java 5, and I didn't pay attention to this in the
"Overview" tag of my plug-in in PDE:

"specifiy the minimum execution environments required to run this plug-in"

I changed this from J2SE-1.5 to JavaSE-1.6, which entailed this change
in MANIFEST.MF: from

Bundle-RequiredExecutionEnvironment: J2SE-1.5
to:
Bundle-RequiredExecutionEnvironment: JavaSE-1.6

I redeployed, and IT WORKED !!!!!

Note that the message :
Missing Constraint: Bundle-RequiredExecutionEnvironment: JavaSE-1.6

was hard to obtain, and even then, it is not very explicit.
A message like this would be better:

Violated Constraint: bundle XXX declares:
Bundle-RequiredExecutionEnvironment: JavaSE-1.6
but Execution Environment is: J2SE-1.5 (incompatible with JavaSE-1.6)

Sorry my previous message had reversed the Java versions:
It should read:

"specifiy the minimum execution environments required to run this plug-in"

I changed this from JavaSE-1.6 to J2SE-1.5, which entailed this change
in MANIFEST.MF: from

Bundle-RequiredExecutionEnvironment: JavaSE-1.6
to:
Bundle-RequiredExecutionEnvironment: J2SE-1.5
