---------------------------------
Summary: multiple_bindings warning impossible to disable on
Windows using wildcard classpath
Key: SLF4J-492
URL: https://jira.qos.ch/browse/SLF4J-492
Project: SLF4J
Issue Type: Bug
Components: slf4j-simple
Affects Versions: 1.7.30
Environment: Windows 10
java 1.8.0_251
scala 2.13.2
Reporter: Phil Walker
Assignee: SLF4J developers list
Classpath consists primarily of jars below a directory, via '-classpath
'c:\opt\uejlib2.13*'
Warning issued by slf4j:
SLF4J: Class path contains multiple SLF4J bindings.
SLF4J: Found binding in
[jar:file:/opt/uejlib2.13/slf4j-nop-1.7.30.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: Found binding in
[jar:file:/c:/opt/uejlib2.13/slf4j-nop-1.7.30.jar!/org/slf4j/impl/StaticLoggerBinder.class]
SLF4J: See [http://www.slf4j.org/codes.html#multiple_bindings] for an
explanation.
SLF4J: Actual binding is of type [org.slf4j.helpers.NOPLoggerFactory]
The two jar paths differ only with respect to one of them having a drive letter
("C:") and the other not. Because of the way the jar was specified (via a
directory wildcard -classpath), there would not appear to be any way to fix
this on the client side.
If the two paths are compared via "java.io.File.getCanonicalPath", the apparent
duplication is removed, making SLF4J less demanding of client code.
By the way, our project only pulls SLF4J in by way of a transitive dependency,
and this spurious warning is quite problematic for us.
Thanks for your consideration!
