Java Maven：执行 wsgen 时找不到 tools.jar

Maven: tools.jar not found when executing wsgen

提问by FeivelFei

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

我尝试jaxws:wsgen从 Windows 8 命令行使用maven 插件，但它失败了：

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

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).

我知道这表明 Maven 在我的 JDK 中找不到 tools.jar 但我不知道如何添加它（当然安装了 JDK）。

Here are some details about my configuration:

以下是有关我的配置的一些详细信息：

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

java -version

mvn -version

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

所以我也尝试在我的 pom.xml 中添加一个配置文件部分：

<profiles>
    <profile>
        <id>default-tools.jar</id>
        <activation>
            <property>

                <value>Sun Microsystems Inc.</value>
            </property>
        </activation>
        <dependencies>
            <dependency>
                <groupId>com.sun</groupId>

                <systemPath>${java.home}/../lib/tools.jar</systemPath>
            </dependency>
        </dependencies>
    </profile>
</profiles>

and execute

并执行

mvn -P default-tools.jar package

but I still get the ClassNotFoundException.

但我仍然得到ClassNotFoundException.

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

也将tools.jar放入我的本地存储库并没有解决我的问题。

Does anybody has an idea what to try next?

有人知道接下来要尝试什么吗？

Thanks!

谢谢！

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.

完整的输出（插件有问题的一些上下文）会很有用。我不完全确定，但我认为 jaxws maven 插件缺少类，而不是您的应用程序，因此您应该将依赖项添加到该插件，而不是您的应用程序。

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

您可以尝试一些事情：由于这是 Java 7，因此将供应商更改为“Oracle Corporation”。

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

另外你确定你有这条路吗？${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.

仅出于测试原因，您可以默认激活此配置文件，看看是否有帮助，进一步缩小问题的范围。

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

Change your wsdl generator from what you are using to:

将您的 wsdl 生成器从您使用的更改为：

<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).

所有配置都相同，但它适用于 Java 7 和 Java 8（以及 openjdk 8，仅供参考）。
