maven-2 - 如何在 maven-jaxb2-plugin 中指定 JAXB 版本？

Question

我需要使用最新版本的 jaxb: 2.2.4-1，但 maven 或 maven-jaxb2-plugin 似乎从 JDK 中选择了那个。

我尝试指定这样的版本:

<configuration>
    <specVersion>2.2</specVersion>
    ...
</configuration>

但日志显示:

[INFO] [jaxb2:generate {execution: common}]
[INFO] Started execution.
[INFO] JAXB API is loaded from the [jar:file:/opt/jdk1.6.0_24/jre/lib/rt.jar!].
[INFO] Detected JAXB API version [2.1].

我尝试向正确版本的 javax.xml.bind:jaxb-api 和 com.sun.xml.bind:jaxb-impl 添加依赖项，但这没有帮助。

<plugins>
    <plugin>
        <groupId>org.jvnet.jaxb2.maven2</groupId>
        <artifactId>maven-jaxb2-plugin</artifactId>
        <version>0.8.0</version>

        <dependencies>
            <dependency>
                <groupId>javax.xml.bind</groupId>
                <artifactId>jaxb-api</artifactId>
                <version>2.2.4</version>
            </dependency>

            <dependency>
                <groupId>com.sun.xml.bind</groupId>
                <artifactId>jaxb-impl</artifactId>
                <version>2.2.4-1</version>
            </dependency>
        </dependencies>

        <executions>
            <execution>
                <id>common</id>
                <goals>
                    <goal>generate</goal>
                </goals>
                <configuration>
                    <specVersion>2.2</specVersion>
                    ...
                </configuration>
            </execution>
        </executions>
    </plugin>
</plugins>

我也尝试使用 maven-jaxb22-plugin 但它也不起作用。

以下代码改编自 netbeans 生成的默认 webapp。它使用依赖插件将 jars 复制到一个临时文件夹，并将该文件夹指定为编译器的认可目录，以便它覆盖 jdk 中的实现。

<properties>
    <endorsed.dir>${project.build.directory}/endorsed</endorsed.dir>
</properties>

...
