cc @adonis0147 this condition always return false now

[adonis0147]

Would you like to provide some steps to reproduce the issue? I ran bash -x run-regression-test.sh on my machine but found the condition passed.

[adonis0147]

Finally, I got the issue which the pr aims at resolving.

When we run run-regression-test.sh, the script always builds the jar for regression test framework even if the jar was built before.
