# rpm -Uvh mercurial-4.9-1.x86_64.rpm

When the home directory for build is / usr / local / src / openjdk8

# cd /usr/local/src
# hg clone http://hg.openjdk.java.net/jdk8u/jdk8u openjdk8u
# cd openjdk8u
# chmod +x get_source.sh
# ./get_source.sh

configure script execution

# cd /usr/local/src/openjdk8u
# chmod +x configure
# ./configure

make script execution

# cd /usr/local/src/openjdk8u
# make images

Verification of the built JDK

Build artifacts are generated under build / linux-x86_64-normal-server-release / images / j2sdk-image (JRE is under j2jre-image) Check and verify the version with the new java command binary generated

# cd /usr/local/src/openjdk8u
# cd ./build/linux-x86_64-normal-server-release/images/j2sdk-image
# ./bin/java -version
