如何在 2.7 中生成 GWT Soyc 报告？

使用以下原型命令创建的 GWT 2.7 maven 项目。

mvn archetype:generate -DarchetypeGroupId=org.codehaus.mojo -DarchetypeArtifactId=gwt-maven-plugin -DarchetypeVersion=2.7.0

我正在尝试为其生成大豆报告。我尝试了 2 种方法，但都未能创建 soyc 报告。此功能是否已废弃。

方法 1 - 我尝试在 pom.xml 中使用配置参数

            <compilerMetrics>true</compilerMetrics>
            <compileReport>true</compileReport>
            <detailedSoyc>true</detailedSoyc>

方法 2 - 我尝试使用 mvn 命令行参数

mvn -Dgwt.compiler.soycDetailed=true clean install

但是，构建通过而没有创建 soyc 并出现以下异常

    【解决方案1】：

    尝试删除详细的 Soyc 参数。我也遇到了这个问题；我生成 SOYC 没问题，然后它开始失败，所以我调整了我的设置，直到我得到 SOYC。启用 json soyc 并禁用详细的 Soyc 后，我仍然可以获得大量详细信息，显示我的编译大小来自何处。

    这是我目前使用的：

    -XjsInteropMode JS -XmethodNameDisplayMode NONE -Xnamespace NONE
-style OBFUSCATED -sourceLevel 1.8 -compileReport -XnocompilerMetrics
-XnocheckCasts -XnoclassMetadata -XclusterFunctions -XinlineLiteralParameters
 -XoptimizeDataflow -noincrementalCompileWarnings -XenableJsonSoyc 
-nooverlappingSourceWarnings -saveSource -soycReport -XnodetailedSoyc 
-optimize 9 -setProperty compiler.stackMode=strip net.wetheinter.webcomponent.GwtcTest

    请注意，其他偶然发现此问题的人，我在 EmptyStackException 上设置了一个 java 异常断点，发现空堆栈似乎发生在 LongLibBase 周围。这可能是一个编译器错误，因为这是一个内部类，通常与其他类不同。

    【讨论】：

    • 为了记录，我也在一个 Maven 容器中运行，尽管是通过 jetty:run。也许 Plexus 类加载器与它有关，但我们会看看是否有其他人参与此事。
    • 由于我正在尝试使用 RPC 和拆分点详细信息获取完整报告，因此我不能忽略 soycDetailed 标志。
    • 您是否尝试过不带该标签并查看您得到的详细信息？如果您仍然无法获得有用的信息，我可以在明天的会议上询问。
