[eclipse-yocto] [yocto] Eclipse Yocto Plugin configuration not saved

[axel.lagrange at oxytronic.fr]

Hi,

I have a configuration problem.

Here are the steps I follow:
Open Window->Preferences->Yocto Project SDK:
· Cross Compiler Options : “Standalone pre-built toolchain”
. Toolchain Root Location: pointing to peta linux external sdk toolchain 
build from yocto ==> the location seems OK because aarch64-xilinx-linux 
appears into target arch
· Sysroot Location : pointing to sysrootfs build by yocto
· Target options: external hw

After clicking on apply & close, the configuration is not saved. When 
going back on Open Window->Preferences->Yocto Project SDK, I find the 
default options

I try with
. eclipse neon and eclipse oxygene,
. on ubuntu LTS 16.O4 and ubuntu 17.10
. java machine java-1.8.0-openjdk-amd64 and java-1.9

Best regards

Axel
