【问题描述】：

尝试使用 NetBeans 构建 mavenized 项目失败：

未能在项目 MyProject 上执行目标 org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.7.5:generate（默认）：

目标 org.jvnet.jaxb2.maven2:maven-jaxb2-plugin:0.7.5:generate failed 的执行默认：

Number of foreign imports: 1

我的 POM.xml 看起来像这样：

<plugin>
    <groupId>org.jvnet.jaxb2.maven2</groupId>
    <artifactId>maven-jaxb2-plugin</artifactId>
    <version>0.7.5</version>
    <executions>
        <execution>
            <goals>
                <goal>generate</goal>
            </goals>
        </execution>
    </executions>

    <configuration>
        <schemaDirectory>src/main</schemaDirectory>
        <schemaIncludes>
            <include>package/aFile.xsd</include>
        </schemaIncludes>
        <generateDirectory>src/generated</generateDirectory>
        <generatePackage>package.jaxb2</generatePackage>
        <readOnly>true</readOnly>
    </configuration>
</plugin>

DirectoryScanner 类是 plexus-utils 的一部分，我已将其列为依赖项并安装在我的本地存储库中。

编辑：显然，如果我添加 plexus-utils 作为 jaxb2 插件的 依赖项，一切正常。

【参考方案1】：

请尝试 0.8.1 版本。以前的版本有this problem的问题，现在应该更正了。
