编译项目时，我得到了这个模糊的异常

Shutting down PersistentUnitCache thread

我可以从哪里开始寻找问题？

Answer 1

请在删除所有生成的存根并再次重新编译项目后再次尝试。

我已经突出显示了需要删除的所有存根，如下面的快照所示。

以下是需要删除的文件夹列表（名称可能因GWT项目编译模块名称而异）。

• gwt-unitCache
• test-classes
• 战争＆gt; gwtproject
• 战争＆gt; WEB-INF＆gt;类
• 战争＆gt; WEB-INF＆gt;部署

Answer 2

在我的情况下，我不得不从我的类路径中删除asm 3.1，并且有几个jar对asm 3.1有内部依赖。我不得不从我的pom中的依赖中排除。例如：

<dependency>
        <groupId>org.apache.cxf</groupId>
        <artifactId>cxf-rt-frontend-jaxws</artifactId>
        <version>2.7.18</version>
        <exclusions>
          <exclusion> <!-- exclude version 3 of asm -->
            <groupId>asm</groupId>
            <artifactId>asm</artifactId>
          </exclusion>

        </exclusions>
      </dependency>

还有其他具有此类内部依赖性的jar，使用maven依赖树来识别。并排除asm依赖。

注意：您甚至可以将这些罐升级到更高版本，这些版本实际上支持更高版本的ASM（> 4.0），这对于GWT 2.7或2.8应该没问题

Answer 3

在我的情况下，我不得不排除来自hibernate验证器库的asm artefact，所以你可以在你的gwt模块的maven配置中排除任何asm artefact。

Answer 4

当我在编译期间在我的类路径上有gwt-servlet.jar时，这发生在我身上。如果使用maven，请将gwt-servlet.jar的依赖关系标记（设置范围）为provided

Answer 5

<dependency>
    <groupId>asm</groupId>
    <artifactId>asm</artifactId>
    <version>4.0</version>
</dependency>

我将asm版本迁移到4.0并解决了问题

Answer 6

当我将gwt从2.6.1迁移到2.8时，我遇到了同样的问题。实际上这个错误是由asm依赖引起的。您的某些服务器依赖项对asm具有内部依赖性。在我的情况下它的cglib。所以我将cglib更改为cglib-nodep并且工作正常： - ）

   <dependency>
        <groupId>cglib</groupId>
        <artifactId>cglib-nodep</artifactId>
        <version>3.2.1</version>
    </dependency>

Answer 7

对我来说，我没有使用gwt-servlet.jar，依赖项引用它的旧版本。我添加了最新的（匹配我的gwt-user.jar）作为常规依赖项，然后Maven知道只使用最新版本。您可以使用 mvn dependency：tree -Dverbose

检查依赖关系树

Answer 8

在我的项目中，模块化GWT应用程序，我不得不将gwt-dev的依赖项添加到启动整个应用程序的模块中。

<dependency>
    <groupId>com.google.gwt</groupId>
    <artifactId>gwt-dev</artifactId>
    <scope>provided</scope>
</dependency>
