由於長類路徑使用Maven的jaxws wsgen插件時，命令行參數太長

Question

我試圖使用org.jvnet.jax-ws-commons jaxws-maven-plugin和wsgen目標生成web服務構件。看起來這個過程的一部分是執行一個命令，該命令包含了類路徑上的所有項目jar，並且這會導致超出命令行字符限制的命令超過兩倍（在Windows 7上）。我該如何解決這個問題？

The command line is too long. 

Answer 1

這是一個已知的bug（JAX-WS-COMMON-110），將在2.3.1版中修復。

直到jaxws-maven-plugin 2.3.1正式發佈，你可以從svn編譯它。

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 

，然後更新您的pom.xml使用2.3.1-B03版：

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

你不需要自己構建更新的版本，它可以從Maven下載資源庫
