java - 如何使用 Maven 构建 ExtJS 项目

Question

我尝试配置 sencha cmd 在 Maven 中使用 mojo 插件。 Maven 配置如下所示:

<plugin>
    <groupId>org.codehaus.mojo</groupId>
    <artifactId>exec-maven-plugin</artifactId>
    <version>1.3.2</version>
    <executions>
        <execution>
            <id>sencha-compile</id>
            <phase>compile</phase>
            <goals>
                <goal>exec</goal>
            </goals>
            <configuration>
                <!-- Set path to your Sencha Cmd executable-->
                <executable>${env.SENCHA_CMD}</executable>
                <arguments>
                    <argument>-sdk</argument>
                    <argument>${basedir}/src/main/webapp</argument>
                    <argument>app</argument>
                    <argument>build</argument>
                    <argument>--clean</argument>
                    <argument>--environment</argument>
                    <argument>${sencha.env}</argument>
                    <argument>--destination</argument>
                    <argument>${basedir}/src/main/webapp/build</argument>
                </arguments>
            </configuration>
        </execution>
    </executions>
</plugin>

我的项目结构如下:

我设置了环境变量 SENCHA_CMD=C:\Users\yura\bin\Sencha\Cmd\5.1.0.26(在我的例子中，我使用的是 Windows 操作系统)。当我尝试执行 mvn:compile 命令时出现错误:

如何修复错误？

Answer 1

事实上，这不是一个直接的答案，但也许它会给你一个想法。这个想法是，在 IOException 的背后有一条用您的语言表示的有用的错误消息。根据我所看到的情况，我假设您来自 Urkaine 并使用 Windows。所以我查找了乌克兰的默认 Windows 代码页。那给我带来了here .由于 java 基于 Unicode 而 Unicode 基于 ISO8859-1，我使用这个小程序重新编码消息。

    byte[] bytes = "Îòêàçàíî â äîñòóïå".getBytes("ISO8859-1");
    System.out.println(new String(bytes, "Windows-1251"));

结果是:

Отказано в доступе

Google 将其翻译为访问被拒绝。

然而，除了这个非常有趣的编码内容之外，我还看到了消息

Cannot run program "C:\Users\yura\bin\Sencha\Cmd\5.1.0.26"

这看起来更像是一个目录，而不是一个命令。这个值可能是错误的吗？
