Error when compiling openjdk8 in centos 6.10

Question

I completely cloned the openjdk8 project.

hg clone http://hg.openjdk.java.net/jdk8u/jdk8u
cd jdk8u/

exec script:

./get_source.sh

These are all executed smoothly.

but,

./configure

error message: /root/jdk8u/common/autoconf/configure: line 197: /root/jdk8u/generated-configure.sh: No such file or directory

[root@localhost jdk8u]# ./configure 
Configure source code has been updated, checking time stamps
Running generated-configure.sh
/root/jdk8u/common/autoconf/configure: line 197: /root/jdk8u/generated-configure.sh: No such file or directory
configure exiting with result code 1
[root@localhost jdk8u]# 

Answer 1

The problem has been solved because the source code is not completely downloaded. Just execute get_source.sh a few times.
