NullPointerException

[karlp]

Unfortunately there's no stack trace, just...

Memory Map Plugin version 2.2.1 (53614)
ERROR: Build step failed with exception
java.lang.NullPointerException
Build step 'Memory Map Publisher' marked build as failure

I added a custom logger for net.praqma.jenkins and got nothing extra there either.

I suspect that the linker script parsing doesn't handle includes? The linker script is just

/* Define memory regions. */
MEMORY
{
	rom (rx) : ORIGIN = 0x08002000, LENGTH = 56K
	ram (rwx) : ORIGIN = 0x20000000, LENGTH = 32K
	eep (r) : ORIGIN = 0x08080000, LENGTH = 4K
}

INCLUDE ../common/cortex-m-generic.ld

However, I don't know how to debug this further

Can you share the Memory Map plugin's configuration of your job? I'll see if I can reproduce the issue.

Reconfigured it from scratch again, and got a stack trace thsi time too...

COnfig is as per image, based on examples in https://github.com/Praqma/memory-map-examples/blob/master/examples/arm-none-eabi-gcc_4.8.4_hello_world/graphConfiguration.json

app.ld is (with comments stripped)

{
	rom (rx) : ORIGIN = 0x08002000, LENGTH = 56K
	ram (rwx) : ORIGIN = 0x20000000, LENGTH = 32K
	eep (r) : ORIGIN = 0x08080000, LENGTH = 4K
}
INCLUDE ../common/cortex-m-generic.ld

cortex-m-generic.ld is https://github.com/libopencm3/libopencm3/blob/master/lib/cortex-m-generic.ld

The parser tries to find the SECTIONS block it assumes is in your app.ld. The following step then happily explodes trying to parse null. So indeed, it boils down to the plugin being unable to handle INCLUDE statements. In the end, it's just a humble jumble of regular expressions.

I'll make an issue about the missing INCLUDE support, though that might take a while to implement. Our Jenkins plugins are mostly on life support as our R&D has all but evaporated. In the mean time, you'll probably need find a workaround, such as appending the files together in an earlier step.
