NoSuchMethodError: BossBar.progress

[forresthopkinsa]

Initially reported in Discord.

While trying to use Adventure's bossbar component, I get a NoSuchMethodError on line 58 of this file.

Exception in thread "Velocity Task Scheduler - #0" java.lang.NoSuchMethodError: net.kyori.adventure.bossbar.BossBar.progress(F)Lnet/kyori/adventure/bossbar/BossBar;

Here is a dump of my Velocity configuration.

In summary:

• Velocity 1.1.2
• Linux x64
• Java 8 u261

Additionally, here's my build script. Maybe I misconfigured something in there?

Tux suggests that Kotlin is causing the problem, and insists that this is not a Velocity issue – so, I'm just gonna open this issue to track my progress on solving it for Kotlin users.

It sounds like you're developing against 1.1.3-SNAPSHOT but running on 1.1.2.

[forresthopkinsa]

I posted my build script above – it looks to me like I'm working with the 1.1.2 API

[forresthopkinsa]

I printed out my Gradle dependency tree, here it is

It suggests that Velocity is trying to pull in adventure-api:4.1.1 but is instead getting 4.3.0

Here's a snip of what looks to me like the culprit:

compileClasspath - Compile classpath for compilation 'main' (target  (jvm)).
...
\--- com.velocitypowered:velocity-api:1.1.2
     ...
     +--- net.kyori:adventure-text-serializer-legacy-text3:4.0.0-SNAPSHOT
     |    \--- net.kyori:adventure-api:4.3.0 (*)
     ...

[zml2008]

Ah yes that makes sense -- that serializer is part of the platform project, so it keeps getting updated. I expect velocity will have to exclude its transitive dependency on newer adventure.

[forresthopkinsa]

As a temporary workaround, @zml2008's suggestion to use BossBar.percent(float) suffices. Thanks for the tip!

[forresthopkinsa]

@astei Thanks! 🎉 What's the ETA for the next release looking like?

[astei]

It will come out when it comes out. I do not give ETAs, I work on this in my free time and when contracted to work on it.

[forresthopkinsa]

I'm just not familiar with the Velocity release cadence
