sbt fails to download jna-4.1.0.jar Connection reset - scala

Question

I have a new SBT/Scala setup with an existing Play/Scala project. When I try and run activator clean in the folder, I get the error below:

[error] (*:update) sbt.ResolveException: download failed: net.java.dev.jna#jna;4
.1.0!jna.jar
Project loading failed: (r)etry, (q)uit, (l)ast, or (i)gnore?
If I try and paste the URL https://repo1.maven.org/maven2/net/java/dev/jna/jna/4.1.0/jna-4.1.0.jar for the jar in my browser, I am able to download the jar.
I tried to delete both .sbt and .ivy folders and then ran the command again, but got the same error.
Not sure what is going on?
Thanks in advance.
Update
I ran the build from activator UI and enabled debug output. Here is what I found:
Activator first tries to download https://repo.typesafe.com/typesafe/ivy-releases/net.java.dev.jna/jna/4.1.0/jars/jna.jar
which really does not exist. Copy and paste the URL in a browser, and it says not found.
It then tries https://repo.scala-sbt.org/scalasbt/sbt-plugin-releases/net.java.dev.jna/jna/4.1.0/jars/jna.jar and fails for the same reason.
It then tries https://repo1.maven.org/maven2/net/java/dev/jna/jna/4.1.0/jna-4.1.0.jar which succeeds and it starts to download, but fails with the error below:

Not sure whats causing that connection reset?
UPDATE 2: It turns out that the jar in question, has a DLL file in it. I'm wondering if it is the Netscaler/Antivirus that is causing the issue. Have logged a call with the Network admins.

Answer 1

I can get information that you did not set the Local Maven Repository as one of your repositories which means your sbt project will not search the dependency in your local maven repository which is a place that storing your maven dependency jars. If your sbt project can not download the jar from internet by itself. You can give a help by doing the following things:
First, add the following statement in your build.sbt
resolvers += ("Local Maven Repository" at "file:///"+Path.userHome.absolutePath+"/.m2/repository")
Second, download the dependency jar by yourself from maven repository. As for your question, the download link is there
Then, publish the jar to your local maven repository by using the following command assuming that the jar file is in the directory ~
mvn install:install-file -Dfile=~/jna-4.1.0.jar -DgroupId=net.java.dev.jna -DartifactId=jna -Dversion=4.1.0 -Dpackaging=jar
Lastly, refresh your sbt project.
if you find mvn command not found, please install it.
A reference which I gived answer to another question may help you.
Good luck
