Failed cronet build

[Goodsol Lee]

Hi, I'm newbee who wanna adopt cronet on my research.

I face the problem while building cronet with command: ninja -C out/Debug cronet_package in https://chromium.googlesource.com/chromium/src/+/refs/tags/63.0.3236.1/components/cronet/android/build_instructions.md. I followed all instructions before facing the error. 

The error log says there is no jar file, but I can't know what is jar file and where is it. The error log is as follows:

root@35f93f51d733:/home/mobisys22/quic/chromium/src# ninja -C out/Debug cronet_package

ninja: Entering directory `out/Debug'

[31/1893] ACTION //components/cronet/android:generate_javadoc(//build/toolchain/android:android_clang_arm)

Thanks in advance.

Hi, I solved the problem with very simple shell command.

With installation of open jdk, problem can be solved.

shell command:  sudo apt-get install openjdk-8-jdk

Hope this may help someone.
