Server errors with jdk8 & ant1.9

[minsiksudo]

Hi,

I ran into this problem while I tried most of the jdk versions and ant 1.10 and ant1.9 several times.

With my Mac, it says

[ivy:retrieve] :::: ERRORS

I am using jdk8

(base) minsikkim@Minsiks-MacBook-Pro RDPTools % java -version
openjdk version "1.8.0_382"
OpenJDK Runtime Environment (Zulu 8.72.0.17-CA-macosx) (build 1.8.0_382-b05)
OpenJDK 64-Bit Server VM (Zulu 8.72.0.17-CA-macosx) (build 25.382-b05, mixed mode)

And I am using ant1.9

(base) minsikkim@Minsiks-MacBook-Pro RDPTools % ant -version
Apache Ant(TM) version 1.9.16 compiled on July 10 2021

Maybe it's because of my firewall settings? Or, does it due to the version issue (2.14 release)? Please let me know how can I resolve this.

++ I tried them with my linux server but I ran into another problem, showing

download-traindata:
      [get] Getting: http://rdp.cme.msu.edu/download/rdpclassifiertraindata/data.tgz
      [get] To: /home/bagel/RDPTools/classifier/build/classes/data.tgz
      [get] Error getting http://rdp.cme.msu.edu/download/rdpclassifiertraindata/data.tgz to /home/bagel/RDPTools/classifier/build/classes/data.tgz

BUILD FAILED
/home/bagel/RDPTools/classifier/build.xml:50: java.net.NoRouteToHostException: No route to host (Host unreachable)
	at java.net.PlainSocketImpl.socketConnect(Native Method)

Currently all my firewalls are off so it shouldn't be a firewall issue.

Thanks in advance,
