Error when downloading PIV from update site

[iuri-cv]

Hi,
I've added the correct URL (https://sites.imagej.net/iterativePIV/) to "Manage update sites" and, after clicking "Apply Changes", got the following error message:

[ERROR] java.io.FileNotFoundException: https://sites.imagej.net/iterativePIV/jars/javacpp-1.4.4.jar-20190625095831 at sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) at sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:62) at sun.reflect.DelegatingConstructorAccessorImpl.newInstance(DelegatingConstructorAccessorImpl.java:45) at java.lang.reflect.Constructor.newInstance(Constructor.java:423) at sun.net.www.protocol.http.HttpURLConnection$10.run(HttpURLConnection.java:1967) at sun.net.www.protocol.http.HttpURLConnection$10.run(HttpURLConnection.java:1962) at java.security.AccessController.doPrivileged(Native Method) at sun.net.www.protocol.http.HttpURLConnection.getChainedException(HttpURLConnection.java:1961) at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1521) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1505) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getInputStream(HttpsURLConnectionImpl.java:268) at net.imagej.updater.util.Downloader.download(Downloader.java:117) at net.imagej.updater.util.Downloader.start(Downloader.java:98) at net.imagej.updater.Installer.start(Installer.java:154) at net.imagej.ui.swing.updater.UpdaterFrame.install(UpdaterFrame.java:627) at net.imagej.ui.swing.updater.UpdaterFrame$13.run(UpdaterFrame.java:564) Caused by: java.io.FileNotFoundException: https://sites.imagej.net/iterativePIV/jars/javacpp-1.4.4.jar-20190625095831 at sun.net.www.protocol.http.HttpURLConnection.getInputStream0(HttpURLConnection.java:1913) at sun.net.www.protocol.http.HttpURLConnection.getInputStream(HttpURLConnection.java:1505) at sun.net.www.protocol.http.HttpURLConnection.getHeaderField(HttpURLConnection.java:3078) at java.net.HttpURLConnection.getHeaderFieldDate(HttpURLConnection.java:552) at java.net.URLConnection.getLastModified(URLConnection.java:559) at sun.net.www.protocol.https.HttpsURLConnectionImpl.getLastModified(HttpsURLConnectionImpl.java:436) at net.imagej.updater.util.Downloader.download(Downloader.java:108) ... 4 more
I'm using ImageJ 1.53t / Java 1.8.0_332
Thanks in advance.
