> The ng-toast error message is still shown as @astroshim said in the above
comment. How about adding some timeout property to the message?
I knew that there is a timeout option for `ng-toast` but I chose not use
it. The simple reason is that I consider the dependency issue is a **serious**
issue so we want the user to **explicitly/manually** close the error popup and
acknowledge that he is aware about the download issue.
What is your opinion about that ? Adding a timeout to automatically close
the error popup is very easy.
> Need to show "Could not find artifact bbb:111.2.2.2 in central
(http://repo1.maven.org/maven2/)" as well if we want to show the number of
errors.
There is a simple explanation for this. `sonatye.aether` library tries to
download the dependencies **one after another** and raise an exception as soon
as it cannot find/download a dependency. In your example, we'll see the error
popup for the 2<sup>nd</sup> dependency if the download of the 1<sup>st</sup>
is successful
```java
synchronized (repos) {
for (RemoteRepository repo : repos) {
collectRequest.addRepository(repo);
}
}
DependencyRequest dependencyRequest = new
DependencyRequest(collectRequest,
DependencyFilterUtils.andFilter(exclusionFilter,
classpathFilter));
try {
return system.resolveDependencies(session,
dependencyRequest).getArtifactResults();
} catch (NullPointerException ex) {
throw new RepositoryException(String.format("Cannot fetch
dependencies for %s", dependency));
}
```
We cannot change the behavior of `sonatype.aether`. We can change our
source code to download dependency **one by one** but it is very slow and
require changing the interface of a lot of methods
