select jdk manuallly

[weifeng233]

i have multiple versions of jdk on my computer, and default is jdk18(i have to use this version for other apps), but the toolchain use java command directly, which will cause error
so maybe it can let user to select the right version jdk's path or download jdk1.8 when installing toolchain
