Looks like problem of configuration for maven compiler in your pom file. Default version java source and target is 1.5, even used JDK has higher version.

To fix, add maven compiler plugin configuration section with higher java version, example:

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.6.1</version>
  <configuration>
    <source>1.6</source>
    <target>1.6</target>
  </configuration>
</plugin>

We can force the checksum validation in maven with at least two options   1 Adding the --strict-checksums to our maven command    2 Adding the following configuration to our maven settings file     lt settings xmlns  http   maven apache org SETTINGS 1 0 0        xmlns xsi  http   www w3 org 2001 XMLSchema-instance        xsi schemaLocation  http   maven apache org SETTINGS 1 0 0                           https   maven apache org xsd settings-1 0 0 xsd  gt       lt  --   -- gt       lt profiles gt           lt profile gt               lt  --   -- gt               lt repositories gt                   lt repository gt                       lt id gt codehausSnapshots lt  id gt                       lt name gt Codehaus Snapshots lt  name gt                       lt releases gt                           lt enabled gt false lt  enabled gt                           lt updatePolicy gt always lt  updatePolicy gt                           lt checksumPolicy gt fail lt  checksumPolicy gt                       lt  releases gt                       lt snapshots gt                           lt enabled gt true lt  enabled gt                           lt updatePolicy gt never lt  updatePolicy gt                           lt checksumPolicy gt fail lt  checksumPolicy gt                       lt  snapshots gt                       lt url gt                           lt  --   -- gt                       lt  url gt                   lt  repository gt               lt  repositories gt               lt pluginRepositories gt                   lt  --   -- gt               lt  pluginRepositories gt               lt  --   -- gt           lt  profile gt       lt  profiles gt       lt  --   -- gt   lt  settings gt    More details in this post  https   dzone com articles maven-artifact-checksums-what

You need to check which jar is giving problem  It must be corrupted  Delete that jar and run mvn spring-boot run command again  May be more that one jar has corrupted so every time you need to run that command to delete that jar  In my case mysql  jackson  aspect jars was corrupted mvn spring-boot run command 3 times and I figure out this and deleted the jars from  m2 folder  Now the issue has resolved

Beyond removing  m2 repository  remove application from server  run server  without applications   stop it and add application again  Now it is supposed to work  For some reason just cleaning up server folders from interface doesn t have the same effect

The mainly problem are corrupted jars   To find the corrupted one  you need to add a Java Exception Breakpoint in the Breakpoints View of Eclipse  or your preferred IDE  select the     java util zip ZipException class  and restart Tomcat instance   When the JVM suspends at ZipException breakpoint you must go to  JarFile getManifestFromReference   in the stack trace  and check attribute name to see the filename   After that  you should delete the file from file system and then right click your project  select Maven  Update Project  check on Force Update of Snapshots Releases

Maybe unrelated to the original reason in this question  but for those who would face same with gradle and local module dependency dependencies       checkstyle project  quot  module quot      this error could happen  if module doesn t contain group and version  so in the module build gradle just need to be specified plugins       id  java-library     group    quot com example quot  version    quot master-SNAPSHOT quot
