Accessing Flume logs on the Windows 11 platform

My log configuration file:

a1.sources = r1
a1.channels = c1
a1.sinks = k1
# Describe/configure the source
a1.sources.r1.type = TAILDIR
#断点续传
#a1.sources.r1.positionFile = D:\\flumedev\\tail_dir.json
# 多目录监控
a1.sources.r1.filegroups = f1 f2
a1.sources.r1.filegroups.f1 = D:\\flumedev\\source\\test2\\asdfile.log
a1.sources.r1.filegroups.f2 = D:\\flumedev\\source\\test1\\test.log

# channal
a1.channels.c1.type = memory
a1.channels.c1.capacity = 1000
a1.channels.c1.transactionCapacity = 100

# Describe the sink
a1.sinks.k1.type = logger

# Bind the source and sink to the channel
a1.sources.r1.channels = c1
a1.sinks.k1.channel = c1

My startup Flume command:
D:\apache-flume-1.11.0-bin>bin\flume-ng agent --conf conf --conf-file D:\\flumedev\\flume-taildir-hdfs.conf --name a1

The error logs I received:

Start with org.apache.flume.source.taildir.ReliableTaildirEventReader.getInode at line 284 and reproduce the failure using the provided Windows 11 configuration and startup command. Check the Taildir source startup path and verify completion when the configured log files can be monitored without the “View 'unix' not available” exception.
