Maven: tools.jar not found when executing wsgen

Question

I try to use jaxws:wsgen maven plugin from Windows 8 command line, but it fails with:

java.lang.ClassNotFoundException: com.sun.mirror.apt.AnnotationProcessorFactory

I know this indicates Maven cannot find tools.jar in my JDK but I don't know how to add this (JDK is installed of course).

Here are some details about my configuration:

echo %JAVA_HOME%
C:\Java\jdk1.7.0_51

java -version
java version "1.7.0_51"
Java(TM) SE Runtime Environment (build 1.7.0_51-b13)
Java HotSpot(TM) 64-Bit Server VM (build 24.51-b03, mixed mode)

mvn -version
Apache Maven 3.1.1 (0728685237757ffbf44136acec0402957f723d9a; 2013-09-17 17:22:22+0200)
Maven home: C:\Program Files (x86)\apache-maven-3.1.1
Java version: 1.7.0_51, vendor: Oracle Corporation
Java home: C:\Java\jdk1.7.0_51\jre
Default locale: de_CH, platform encoding: Cp1252
OS name: "windows 8", version: "6.2", arch: "amd64", family: "windows"

So I also tried to add a profile section to my pom.xml:

<profiles>
    <profile>
        <id>default-tools.jar</id>
        <activation>
            <property>
                <name>java.vendor</name>
                <value>Sun Microsystems Inc.</value>
            </property>
        </activation>
        <dependencies>
            <dependency>
                <groupId>com.sun</groupId>
                <artifactId>tools</artifactId>
                <version>1.7.0</version>
                <scope>system</scope>
                <systemPath>${java.home}/../lib/tools.jar</systemPath>
            </dependency>
        </dependencies>
    </profile>
</profiles>

and execute

mvn -P default-tools.jar package

but I still get the ClassNotFoundException.

Full output:

Also putting the tools.jar into my local repository did not solve my problem.

Does anybody has an idea what to try next?

Thanks!

Answer 1

The full output (some context what plugin is having problems) would be useful. I'm not entirely sure, but I think that the jaxws maven plugin is missing the classes, not your application, so you should add the dependency to that plugin, not your application.

EDIT: OP's code from comment for better read/copy/paste-ability

<plugin>
 <groupId>org.codehaus.mojo</groupId>
 <artifactId>jaxws-maven-plugin</artifactId>
 <...>
 <dependencies>
  <dependency>
   <groupId>com.sun</groupId>
   <artifactId>tools</artifactId>
   <version>1.7</version>
   <scope>system</scope>
   <systemPath>${java.home}/../lib/tools.jar</systemPath>
  </dependency>
 </dependencies>
</plugin>

Answer 2

A few thing you can try: since this is java 7 change the vendor to "Oracle Corporation".

Also are you sure you have this path? ${java.home}/../lib/tools.jar

For testing reason only, you could activate this profile by default and see if that helps, further narrowing the problem.

<activation>
  <activeByDefault>true</activeByDefault>
</activation>

Answer 3

Change your wsdl generator from what you are using to:

<plugin>
    <groupId>org.jvnet.jax-ws-commons</groupId>
    <artifactId>jaxws-maven-plugin</artifactId>
    <version>2.2</version>
</plugin>

All the configuration is the same, but it works with Java 7 & Java 8 (and openjdk 8, fyi).
