logstash not starting up in windows 10 pro - ELK stack

Question

I am new to ELK stack. I have installed ELK stack in Windows. The Elastic Search and kibana works great. But when i started logstash, it shows the following error.

When i started the logstash:

C:\Program Files\logstash-6.7.0\logstash-6.7.0\bin>logstash.bat
Picked up _JAVA_OPTIONS: -Xmx1024M
Java HotSpot(TM) 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
Error: Could not find or load main class Files\logstash-6.7.0\logstash-6.7.0\logstash-core\lib\jars\animal-sniffer-annotations-1.14.jar;C:\Program
Caused by: java.lang.ClassNotFoundException: Files\logstash-6/7/0\logstash-6/7/0\logstash-core\lib\jars\animal-sniffer-annotations-1/14/jar;C:\Program

When i tried to pass data via logstash:

C:\Program Files\logstash-6.7.0\logstash-6.7.0\bin>logstash -f logstash_apps.config
Picked up _JAVA_OPTIONS: -Xmx1024M
Java HotSpot(TM) 64-Bit Server VM warning: Option UseConcMarkSweepGC was deprecated in version 9.0 and will likely be removed in a future release.
Error: Could not find or load main class Files\logstash-6.7.0\logstash-6.7.0\logstash-core\lib\jars\animal-sniffer-annotations-1.14.jar;C:\Program

I searched the missing file animal-sniffer-annotations-1.14.jar in the logstash directory. It was there in the bin folder. I tried searching stackoverflow and google but can't find a proper solution. Anyone give me some solutions to solve the problem.

It seems that the problem is being caused by the space in the directory name, as the log shows, it is not looking in C:\\Program Files , but in Files\\ .

Error: Could not find or load main class Files\logstash-6.7.0\logstash-6.7.0\logstash-core\lib\jars\animal-sniffer-annotations-1.14.jar

Move your Logstash installation to a directory without spaces in the name.
