Not able to build a jar in google Cloud Build - spring-boot

Question

I am new to google cloud, I am building an application with maven. In my maven repository I have lib folder where I have didisoft jar files.
I have added the plugins in maven to add them in the classpath. Locally, I am able to build the project but when same steps are executing on cloud build, the 'mvn clean install' fails.
