Maven trouble when trying to generate from WSDL fi

问题:

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

回答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.

回答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.

回答3:

In my case, I fixed it by changing the JAXB specification version as instructed in the plugin wiki:

https://github.com/highsource/maven-jaxb2-plugin/wiki/Using-a-Specific-JAXB-Version

Either by using the config option specVersion=2.0 or by using the version-specific plugin: maven-jaxb20-plugin

回答4:

For me this is a environment (java runtime) problem. I could solve similar issue triggered by m2e in my context, by launching eclipse in Windows command prompt : eclipse.exe -vm "C:\Program Files\Java\jdk1.8.0_25\bin\javaw.exe" (ensure it comes before "-vmargs") Then i tried to clean up my eclipse.ini in the same way to launch eclipse from explorer, it does work. When I have look at the eclipse command in Javavisual VM I see through Jvisual vm that eclipse looks that way

eclipse.commands=-os
win32
...
-vm "C:\Program Files\Java\jdk1.8.0_25\bin\javaw.exe"
-vm C:\Program Files\Java\jre1.8.0_25\bin\server\jvm.dll

Last line does not come from my eclipse.ini, but was appended by Eclipse launcher.In the system prooperties: eclipse.vm=C:\Program Files\Java\jre1.8.0_25\bin\server\jvm.dll This looks like "when launched from explorer", Eclipse luna appends parameter from jre found on the PATH which overrides eclipse.ini... There must be some difference in the environment that can account for the different behaviour of the process.

I had this problem, but I was able to solve it:

1. I deleted ALL single JRE file (previous and current versions)
2. Added to "Path" C:\Program Files\Java\jdk1.8.0_91\jre\bin (I work on Win10)
3. Profit.

Problem was on version 0.12.2 - 0.13.1 and it totally disappeared.

Add

<dependency>
    <groupId>com.sun.xml.bind</groupId>
    <artifactId>jaxb-impl</artifactId>
    <version>2.2.11</version>
</dependency>

to your pom, it contains the missing class, with this I fixed it.
