java - Maven:执行 wsgen 时找不到 tools.jar

Question

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

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

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)。

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
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"

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>
                <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>

并执行

mvn -P default-tools.jar package

但我仍然得到 ClassNotFoundException。

完整输出:

将 tools.jar 放入我的本地存储库也没有解决我的问题。

有人知道接下来要尝试什么吗？

谢谢!

Answer 1

完整的输出(某些插件有问题的上下文)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。
