I got this error   quot Source option 5 is no longer supported  Use 6 or later quot  after I changed the pom xml  lt java version gt 7 lt  java version gt   to  lt java version gt 11 lt  java version gt   Later to realise the property was used with a dash insteal of a dot     lt source gt   java-version  lt  source gt     lt target gt   java-version  lt  target gt    swearings   I replaced the dot with a dash and the error went away   lt java-version gt 11 lt  javaversion gt

There can be corrupted jar file for which it may show error as  ZipFile invalid LOC header  bad signature   You need to delete all jar files for which it shows the error and add this Dependency    lt dependency gt       lt groupId gt javax servlet lt  groupId gt       lt artifactId gt servlet-api lt  artifactId gt       lt version gt 3 0-alpha-1 lt  version gt       lt scope gt provided lt  scope gt   lt  dependency gt

This error might be also for plugin versions  You can fix it in the  POM file like the followings    lt build gt       lt plugins gt           lt plugin gt               lt groupId gt org apache maven plugins lt  groupId gt               lt artifactId gt maven-compiler-plugin lt  artifactId gt               lt version gt 2 3 1 lt  version gt               lt configuration gt                   lt source gt 1 6 lt  source gt                   lt target gt 1 6 lt  target gt               lt  configuration gt           lt  plugin gt       lt  plugins gt   lt  build gt

I think this means that   You are using JDK9 or later Your project uses maven-compiler-plugin with an old version which defaults to Java 5    You have three options to solve this   Downgrade to JDK7 or JDK8  meh  Use maven-compiler-plugin version or later  because     NOTE  Since 3 8 0 the default value has changed from 1 5 to 1 6   See https   maven apache org plugins maven-compiler-plugin compile-mojo html target    lt plugin gt       lt groupId gt org apache maven plugins lt  groupId gt       lt artifactId gt maven-compiler-plugin lt  artifactId gt       lt version gt 3 8 0 lt  version gt   lt  plugin gt   Indicate to the maven-compiler-plugin to use source level 6 and target 6  or later    Best practice recommended by https   maven apache org plugins maven-compiler-plugin      Also note that at present the default source setting is 1 6 and the default target setting is 1 6  independently of the JDK you run Maven with    You are highly encouraged to change these defaults by setting source and target as described in Setting the -source and -target of the Java Compiler     lt plugin gt       lt groupId gt org apache maven plugins lt  groupId gt       lt artifactId gt maven-compiler-plugin lt  artifactId gt       lt configuration gt           lt source gt 1 6 lt  source gt           lt target gt 1 6 lt  target gt       lt  configuration gt   lt  plugin gt    or use   lt properties gt     lt maven compiler source gt 1 6 lt  maven compiler source gt     lt maven compiler target gt 1 6 lt  maven compiler target gt   lt  properties gt

For me the solution was to set the version of the maven compiler plugin to 3 8 0 and specify the release  9 for in your case  11 in mine        lt plugin gt         lt artifactId gt maven-compiler-plugin lt  artifactId gt         lt version gt 3 8 0 lt  version gt         lt configuration gt           lt release gt 11 lt  release gt         lt  configuration gt       lt  plugin gt
