Maven trouble when trying to generate from WSDL file

Question

Im trying to generate sources from a wsdl file, but I keep running into an error on my pom.xml that I believe might be my issue? Below is the error that I get from my pom, and my pom file. Also I cannot build the project with "mvn clean install". I just seem to get an error with no real cause.

The error at the generates tag:

Execution default of goal org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.12.3:generate failed: A required class was missing while executing org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.12.3:generate: com/sun/codemodel/CodeWriter ----------------------------------------------------- realm =    plugin>org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.12.3-715230752 strategy = org.codehaus.plexus.classworlds.strategy.SelfFirstStrategy urls[0] = file:/C:/Users/Windows/.m2/repository/org/jvnet/jaxb2/maven2/maven-jaxb2-plugin/0.12.3/maven-jaxb2-plugin-0.12.3.jar urls[1] = file:/C:/Users/Windows/.m2/repository/org/jvnet/jaxb2/maven2/maven-jaxb2-plugin-core/0.12.3/maven-jaxb2-plugin-core-0.12.3.jar urls[2] = file:/C:/Users/Windows/.m2/repository/org/slf4j/slf4j-api/1.7.7/slf4j-api-1.7.7.jar urls[3] = file:/C:/Users/Windows/.m2/repository/org/apache/commons/commons-lang3/3.2.1/commons-lang3-3.2.1.jar urls[4] = file:/C:/Users/Windows/.m2/repository/com/sun/org/apache/xml/internal/resolver/20050927/resolver-20050927.jar urls[5] = file:/C:/Users/Windows/.m2/repository/junit/junit/4.8.1/junit-4.8.1.jar urls[6] = file:/C:/Users/Windows/.m2/repository/org/codehaus/plexus/plexus-utils/1.5.15/plexus-utils-1.5.15.jar urls[7] = file:/C:/Users/Windows/.m2/repository/org/jvnet/jaxb2/maven2/maven-jaxb22-plugin/0.12.3/maven-jaxb22-plugin-0.12.3.jar urls[8] = file:/C:/Users/Windows/.m2/repository/org/glassfish/jaxb/jaxb-runtime/2.2.11/jaxb-runtime-2.2.11.jar urls[9] = file:/C:/Users/Windows/.m2/repository/org/glassfish/jaxb/jaxb-xjc/2.2.11/jaxb-xjc-2.2.11.jar urls[10] = file:/C:/Users/Windows/.m2/repository/org/apache/maven/plugin-tools/maven-plugin-annotations/3.2/maven-plugin-annotations-3.2.jar Number of foreign imports: 5 import: Entry[import org.sonatype.plexus.build.incremental from realm ClassRealm[plexus.core, parent: null]] import: Entry[import org.codehaus.plexus.util.Scanner from realm ClassRealm[plexus.core, parent: null]] import: Entry[import org.codehaus.plexus.util.DirectoryScanner from realm ClassRealm[plexus.core, parent: null]] import: Entry[import org.codehaus.plexus.util.AbstractScanner from realm ClassRealm[plexus.core, parent: null]] import: Entry[import  from realm ClassRealm[maven.api, parent: null]]  -----------------------------------------------------  (org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.12.3:generate:default:generate-sources)

Answer 1

Enclosing the <plugins> tag inside <pluginManagement> tag (as detailed here: How to solve "Plugin execution not covered by lifecycle configuration" for Spring Data Maven Builds) fixed the issue for me.

Answer 2

Change your Java Path jre to your jdk path and it will be fine! In Eclipse you can also change your "Installed JRE" to your jdk.

Hope it will work for you.
