回答1:

I'd stopped at same error. Finally, I found my stupid mistake that I forgot to add PATH of jar command. The following command is needed in addition to the java set up guide in Chromium official build instructions.

sudo update-alternatives --install /usr/bin/jar jar /usr/lib/jvm/jdk1.6.0_xx/bin/jar 50000

You must install the depot_tools package. Try this commands;

git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
export PATH=$PATH:/path/to/depot_tools
