无法使用 2.8.0-SNAPSHOT 和 Java 8 与 gwt-maven-plugin 编译 GWT 应用程序
Can't compile GWT app using 2.8.0-SNAPSHOT and Java 8 with gwt-maven-plugin
我正在努力让我的应用程序使用 GWT 2.8.0-SNAPSHOT 和 Mojo's gwt-maven-plugin 2.8.0-SNAPSHOT
进行编译
我每次都收到相同的编译器错误：

我不知道这是否是 Java 8、GWT 或 GWTP 的问题。
如能就如何进一步调查或可能导致问题的原因提出任何建议，我们将不胜感激。

更新答案。正如问题作者根据评论发现的那样，问题是由 excel-streaming-reader.
提取的不兼容的 Xerces 库引起的
要解决类似问题，将 -X 传递给 Maven 以检查编译期间使用的所有库并通过 maven-compiler-plugin 中的 logLevel 属性 打开日志记录有助于缩小此类问题的范围。
在我原来的回答中我也建议手动创建
HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs 或 HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Prefs 在 64 位 WinPC 上。
您可以找到其他详细信息，例如在这个 post how to create Prefs root node
GWT 尝试访问 Windows 注册表以通过 java.util.prefs.WindowsPreferences 存储或检索加密密钥数据。这个警告很烦人，但基本上是无害的，除非你喜欢你的日志干净，否则你可以跳过这部分。
正在升级 到答案。
我发现库 excel-streaming-reader 依赖于 xercesImpl 2.4.0（自 2006 年起）。
我声明了对 2.11.0 的额外依赖以解决问题：
<dependency>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
<version>2.11.0</version>
</dependency>
我已将问题通知店主。 Github 问题：https://github.com/monitorjbl/excel-streaming-reader/issues/44

我不知道这是否是 Java 8、GWT 或 GWTP 的问题。
如能就如何进一步调查或可能导致问题的原因提出任何建议，我们将不胜感激。

更新答案。正如问题作者根据评论发现的那样，问题是由 excel-streaming-reader.
提取的不兼容的 Xerces 库引起的要解决类似问题，将 -X 传递给 Maven 以检查编译期间使用的所有库并通过 maven-compiler-plugin 中的 logLevel 属性 打开日志记录有助于缩小此类问题的范围。
在我原来的回答中我也建议手动创建
HKEY_LOCAL_MACHINE\Software\JavaSoft\Prefs 或 HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Prefs 在 64 位 WinPC 上。
您可以找到其他详细信息，例如在这个 post how to create Prefs root node
GWT 尝试访问 Windows 注册表以通过 java.util.prefs.WindowsPreferences 存储或检索加密密钥数据。这个警告很烦人，但基本上是无害的，除非你喜欢你的日志干净，否则你可以跳过这部分。
正在升级
我发现库 excel-streaming-reader 依赖于 xercesImpl 2.4.0（自 2006 年起）。
我声明了对 2.11.0 的额外依赖以解决问题：
<dependency>
<groupId>xerces</groupId>
<artifactId>xercesImpl</artifactId>
<version>2.11.0</version>
</dependency>
我已将问题通知店主。 Github 问题：https://github.com/monitorjbl/excel-streaming-reader/issues/44
