Epitweetr downloading of dependencies in the Shiney App stuck on "Pending" Status

[venomjackal]

Hi All,

I am hoping someone here can assist with having issues trying to get past the downloading of dependencies in the Shiney App.

They are just stuck saying pending and I cannot start the epitweetr database as per the screenshot:

I have carried out the following steps to install and configure epitweetr:

• Using Windows 10 Enterprise machine version 21H2
• Install the latest version of R-4.2.1 for Windows
• Microsoft Visual C++ 2013 Redistributable (x64 is already installed)

Run 64 bit version of R as administrator

Check the Java directory (Java SE Development kit 18.0.2 64bit is installed)

Sys.getenv("JAVA_HOME") "C:\Program Files\Java\jdk-18.0.2"

Install the following using CRAN repository ( R> Install packages) • UK Mirror London 1 Mirror • Select epitweetr (downloads and installs w/o errors) • Select taskScheduleR (downloads and installs w/o errors) • Select rtweet (downloads and installs w/o errors) • Select TinyTex (downloads and installs w/o errors)

Double checked these are installed by running "Installed.packages ()" and I can see them all installed

In R console I run epitweetr & Shiney App

library(epitweetr) epitweetr_app("data_dir")

This created folder in my user profile area C:\Users%username%\Documents\data_dir . It has the following files (fs.PID, fs_mon.PID, and properties.json)

The command opens Shiney App in Firefox (Tried in Edge as the well same issue)

Go to Configuration can see the following URL's

GeoNames URL http://download.geonames.org/export/dump/allCountries.zip Maven repository https://repo1.maven.org/maven2 Winutils URL https://github.com/steveloughran/winutils/raw/master/hadoop-3.0.0/bin/winutils.exe

Troubleshoot option > Diagnostics > run diagnostics returns error "Warning: Error in get_token: Cannot get a token. Please create it from the configuration page"

Try and activate the database from GUI nothing happens

I can see the task scheduler has created the following:

• Epitweetr_fs_loop
• Epitweetr_search_loop
• Spitweetr_detect_loop

If I try and manually run the database activation in R Console I get the following error:

library(epitweetr) fs_loop("data_dir")

Launching fs Exception in thread "main" java.lang.NoClassDefFoundError: scala/collection/Seq at org.ecdc.twitter.Tweets.main(Tweets.scala) Caused by: java.lang.ClassNotFoundException: scala.collection.Seq at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:641) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:188) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:521) ... 1 more The epitweetr Scala API was stopped with the following error Error in spark_job(paste("fsService", "epiHome", conf$data_dir)): Error encountered while exeuting:

It seems to me for some reason the dependencies are not downloading.
