Error while getting repo2.maven to /root/.ant/lib/ivy.jar

[daywin94]

Hello,

I tried to solve this issue for a couple of hours but nothing worked for me.
I tired to build the tools with sudo make but everytime I am running into the same issue (see below)

ant -f Clustering/build.xml jar
Buildfile: /home/davin/Documents/RDPTools/Clustering/build.xml

download-ivy:
[get] Getting: http://repo2.maven.org/maven2/org/apache/ivy/ivy/2.1.0-rc2/ivy-2.1.0-rc2.jar
[get] To: /root/.ant/lib/ivy.jar
[get] Error getting http://repo2.maven.org/maven2/org/apache/ivy/ivy/2.1.0-rc2/ivy-2.1.0-rc2.jar to /root/.ant/lib/ivy.jar

I tried to clone the repository to my home and ran it again. I also installed JDK version 8 and I made sure my ant version is up to date. Nothing seems to work from the other solutions I found so I opened this issue here.

Thanks in advance for any help!

I think this is because the URL is no longer valid for. I was able to solve this by changing the first part of the link on line 26 of the build.xml file to 'https://repo1.maven.org/maven2/org/apache/ivy/ivy/'

I hope that works for you!
