No SLF4J providers were found - how to add a provider?

[Phillipus]

Hi,

we have an Eclipse-base RCP application that uses JGit as a plug-in. When JGit is instantiated the following appears in the console:

SLF4J(W): No SLF4J providers were found.
SLF4J(W): Defaulting to no-operation (NOP) logger implementation

How do I add a SLF4J provider that JGit can use? I tried adding slfj4.simple to the classpath and to the dependencies in our app, but that isn't working.

It seems that extra stuff has to be added to the product.

See eclipse-platform/eclipse.platform.releng.aggregator#1094
See eclipse-platform/eclipse.platform.releng.aggregator#1226
See eclipse-platform/eclipse.platform.releng.aggregator@b9cb479

The changes required can be seen in this commit.

Edit: startLevel="2" is required. See here

The full file is here.

1. Edit your product file
2. Add two entries to the Configuration Start Levels:
   <plugin id="org.apache.aries.spifly.dynamic.bundle" autoStart="true" startLevel="2" />
<plugin id="slf4j.simple" autoStart="true" startLevel="2" />
3. Optionally add -Dorg.slf4j.simpleLogger.defaultLogLevel=off to the Launching VM Arguments

@Phillipus : could you please add a summary of what is missing / what need to be done, because it is almost impossible to get a straight answer looking on longer threads in the list above?
