I am not able to install Java-7
on Google Cloud Engine
. Initially i added a ppa
repository:
sudo add-apt-repository ppa:webupd8team/java
sudo apt-get update
Got this:

E: Some index files failed to download. They have been ignored, or old ones used
instead.
To make sure why apt-get update
is not working. I removed /etc/apt/sources.list.d/
webupd8team-java-wheezy.list
and then run apt-get update
. Everything works fine!
Now, Is there any other way to install java-7
on remote machine using CLI
. I googled but didn't find any relevant info upon it (except installing java-7 manually).
If you don't have an specific requirement to use Java 7 you could install Java 8 with the webupd8 repository in you Debian version. The steps are quite different from the ones you followed for the Java 7 version, though.
As you probably know, having JDK 8 installed doesn't mean your application needs to be JRE 8 compliant: you can set the compliance level in Eclipse (or your IDE) at any time.
