Just a new spring-boot program, automatic finish line first jar package instant pom.xml on the error
Look under the column markers eclipse errors are found Unknown Error
pom.xml there is no effective information
A lot of information in the online search, finally found a new project directly maven repository is no 2.1.5 version of spring-boot-starter-parent package. The reason being given is too high into the jar package version 2.1.1 to address
so here changed to 2.1.1 and then on ok
