Question

我正在尝试使用org.jvnet.jax-ws-commons jaxws-maven-plugin和wsgen目标生成Web服务工件。似乎该过程的一部分是执行包含类路径上所有项目jar的命令，这导致命令超过命令行的字符限制两倍以上（在Windows 7上）。我该如何解决这个问题？

The command line is too long.

Answer 1

这是一个已知错误（JAX-WS-COMMON-110），将在版本2.3.1中修复。

直到jaxws-maven-plugin 2.3.1正式发布，你可以从svn编译它。

svn checkout https://svn.java.net/svn/jax-ws-commons~svn/tags/jaxws-maven-plugin-2.3.1-b03
cd jaxws-maven-plugin-2.3.1-b03
mvn install

然后更新您的pom.xml以使用2.3.1-b03版本：

<plugin>
    <groupId>org.jvnet.jax-ws-commons</groupId>
    <artifactId>jaxws-maven-plugin</artifactId>
    <version>2.3.1-b03</version>
...
</plugin>

Answer 2

您不需要自己构建更新版本，可以从Maven存储库下载

http://search.maven.org/#artifactdetails|org.jvnet.jax-ws-commons|jaxws-maven-plugin|2.3.1-b03|maven-plugin

使用Maven的jaxws wsgen插件时命令行参数太长，因为类路径很长
