java - 无法再编译 Vaadin 项目(无法执行 objective-c om.vaadin :vaadin-maven-plugin )

Question

我有一个 Vaadin 8.6.1 项目，到目前为止一直没有任何问题，突然编译失败:代码或 pom 中的任何内容都没有更改。

我运行的命令是 clean package -e ，但即使我启动 jetty:run 问题也是一样的

这是错误堆栈跟踪

但是如果我尝试启动 mvn vaadin:update-widgetset ，它不会出现错误。

这些是我的 pom 的相关部分:

<properties>
    <vaadin.version>8.6.1</vaadin.version>
    <vaadin.plugin.version>8.6.1</vaadin.plugin.version>
    <jetty.plugin.version>9.4.11.v20180605</jetty.plugin.version>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.8</maven.compiler.source>
    <maven.compiler.target>1.8</maven.compiler.target>
</properties>

这是vaadin插件

<plugin>
            <groupId>com.vaadin</groupId>

            <artifactId>vaadin-maven-plugin</artifactId>
            <version>${vaadin.plugin.version}</version>
            <executions>
                <execution>
                    <goals>
                        <goal>update-theme</goal>
                        <goal>update-widgetset</goal>
                        <goal>compile</goal>
                        <goal>compile-theme</goal>

                    </goals>
                </execution>
            </executions>
            <configuration>
                <gwtSdkFirstInClasspath>true</gwtSdkFirstInClasspath> 
            </configuration>
        </plugin>

我可以做什么来解决这个问题？我找不到解决这个问题的方法。我正在使用 IntelliJ Idea x64、Java 1.8、Windows 7

Answer 1

经过多次尝试，我发现问题出在我们公司的代理上。

将我的笔记本电脑与公司网络断开连接，并将其连接到外部，直接连接到互联网后，我可以毫无问题地进行编译。

我已与 Vaadin 支持人员交谈，他们猜测许可证正在尝试联系 Vaadin 服务器以验证其是否有效，但最终出现此错误，该错误并未涉及此失败的连接。

事实上，成功编译后，我能够再次编译，甚至在代理后面。
