GWT 2.8 无法使自定义链接器正常工作

Question

我有一个自定义链接器来生成一个清单文件，该文件曾经在GWT 2.7之前可以正常工作。 当我更改为GWT 2.8时，我注意到它停止生成文件myapp.manifest。

在模块.gwt上.xml我有

<?xml version="1.0" encoding="UTF-8"?>
<module>
<inherits name="com.google.gwt.user.User" />
<inherits name="com.google.gwt.core.Core" />
<source path="client" />
<source path="shared" />
<source path="constants" />
<entry-point class="br.com.universo.client.AppStart" />
<extend-property name="locale" values="pt" />
<extend-property name="locale" values="en" />
<set-property-fallback name="locale" value="en" />
<define-linker class="br.com.universo.AppManifest"
name="manifest" />
<add-linker name="manifest" />

</module>

这是 2.7 上的编译日志

在GWT 2.8上，我正在使用tbroyer gwt maven原型模块化网络应用程序。 链接器类在客户端模块下定义，但在外部的包上

<source path="client" />

在编译日志上，我没有看到以下行：

[INFO] MyApp OffLine Linker started
[INFO] MyApp OffLine Linker ended

我想这表明它没有被调用？

EmittedArtifact manifest = emitString(logger, builder.toString(), "myapp.manifest");
artifactset.add(manifest);
System.out.println("MyApp OffLine Linker ended");
return artifactset;
}
}

任何帮助都非常感谢！

我终于让它改变了我的AppManifast.java。 我在当前文档中注意到，使用@Shardable注释时，您必须覆盖其他链接方法签名，因此我在类中添加了以下行：

@Override
public ArtifactSet link(TreeLogger logger, LinkerContext context, ArtifactSet artifacts, boolean onePermutation) throws UnableToCompleteException {
return link(logger, context, artifacts);
}

我花了很长时间才发现...
