using boolean variables in filter [message #1740329]

Hello Guys,

I want to include or respectively exclute tasks from beeing triggered if a certain boolean flag is set.

is declared the flag via

<setupTask
        xsi:type="setup:VariableTask"
        id="bitness.is64"
        type="BOOLEAN"
        name="bitness.is64"
        defaultValue="true"
        storageURI="scope://Installation"
        label="64-Bit Software">
      <description></description>
    </setupTask>

and try to use it in that way:

filter="(bitness.is64=true)"

but this doesn't seem to work. Using just 'bitness.is64' yields an error by eclipse.

Can you help me here?

Greetings and Thanks in advance
Steffen

Steffen,

You can only use environment and system properties in a filter, not the
value of a variable. One trick (if the task doesn't need to perform at
bootstrap time) is an Eclipse Ini task to set a -D system property into
the installation's eclipse.ini.

But for this case, you should use the osgi.arch value and look at
org.eclipse.core.runtime.Platform.ARCH_* for the values that are for 64
bit architectures. You use (!(...)(...)) for each of those values in
the filter.
