I have been trying to add the 2.0.16-SNAPSHOT version as a dependency to my
application, but I keep having issues. I added this to my pom file:
<repositories>
<repository>
<id>repository.apache.org.snapshots</id>
<name>Apache snapshots repo</name>
<url>https://repository.apache.org/content/groups/snapshots/</url>
<snapshots>
<enabled>true</enabled>
</snapshots>
<releases>
<enabled>false</enabled>
</releases>
</repository>
</repositories>
And then I added this under dependencies:
<dependency>
<groupId>org.apache.pdfbox</groupId>
<artifactId>pdfbox</artifactId>
<version>2.0.16-SNAPSHOT</version>
</dependency>
When I run “mvn compile” I get this error:
[ERROR] Failed to execute goal on project pdftextextractor: Could not resolve
dependencies for project nu.optimise:pdftextextractor:jar:1.0: Failed to

I am probably missing something obvious, but I haven’t been working with Java
for that long, so I have no clue what to do (my googling skills did not
prevail).
Do you have any tips?
Thanks a lot in advance!
Best regards,
Søren
