How to Install Oracle JDK 11 on Antergos Gnu/Linux

Oracle JDK 11 Antergos Linux - Setting Up

3. 3. Setting Up JDK

   Next to Relocate JDK 11 into the Target
   First, Check that the needed Folder is there:

   if [ ! -d "/usr/lib/jvm" ]; then mkdir /usr/lib/jvm; fi

   Next Extract the Archive directly into the Destination with:

   sudo tar xvzf ~/Downlads/jdk-11*.tar.gz -C /usr/lib/jvm/

   Now Set the SuperUser as owner:

   sudo chown -R root:root /usr/lib/jvm/jdk-11*

   Finally, reiterate the Execution Permission over the Java binaries:

   sudo chmod -R +x /tmp/jdk-11*/bin

4. 4. Making Symlinks

   Follow to Setup the Needed Symlinks
   First, to Copy the Exact Path to Insert in File:

   cd /usr/lib/jvm/jdk-11*

   pwd

   After the Next Commands come back and Select Copy this Output…
   To Copy on Terminal Ctrl+Shift+c.
   Then Relaese the potentially existing Symlinks:

   cd ..

   sudo unlink default

   sudo unlink default-runtime

   So now for the JDK make:

   sudo ln -s [copiedJdkPath] default

   Ctrl+Shift+v to Paste the Path Copied from the above Output.
   And again for the Java Runtime Environment:

   ln -s [copiedJdkPath] default-runtime

   With this you Should be Done! ;)

5. 5. Setting Up Env Vars

   Again SetUp the JDK 11 Environment Variables
   Make Use of the same Path as on the preceding Step…
   And to Edit the Config File:

   nano /etc/profile.d/oracleJDK11.sh

   Copy and Paste into something like that:

   /nexport J2SDKDIR=[copiedJdkPath]/nexport J2REDIR=$J2SDKDIR/jre/nexport JAVA_HOME=$J2SDKDIR/
   

   Again take Care to Replace the [copiedJdkPath] with the Actual one!
   Ctrl+x to Save & Exit from nano Editor :)
   Finally, do the Same also for the csh Shell:

   nano /etc/profile.d/oracleJDK11.csh

   setenv J2SDKDIR=[copiedJdkPath]
   setenv J2REDIR=$J2SDKDIR/jre
   setenv JAVA_HOME=$J2SDKDIR/
   

6. 6. Testing Installation

   Finally, Test Oracle JDK Java Setup.

   javac -version

   On the Output simply must Not be present an Openjdk to Certify it…
