Right click on created project -> New -> Other... -> XML File -> Next -> Put "/src/META-INF" after your project name in "Enter or select the parent folder" field -> set filename to "persistence.xml" -> finish -> replace the content in created xml file with this: <?xml version= "1.0" encoding= "UTF-8" ?> <persistence version= "2.2" xmlns= "https: //java.sun.com/xml/ns/persistence" xmlns:xsi= "https://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" https: //www.oracle.com/webfolder/technetwork/jsc/xml/ns/persistence/ https: //www.oracle.com/webfolder/technetwork/jsc/xml/ns/persistence/persistence_2_2.xsd"> <persistence-unit name= "primary" transaction-type= "JTA" > </persistence-unit> </persistence> save file 4. Right click created project -> Maven -> Update project.. -> check "Force Update of Snapshots/Releases" -> OK 5.
