我在 Eclipse 中创建了 maven 项目并添加了一些依赖项。

以下是完整的依赖项列表：

<dependencies>
    <dependency>
        <groupId>javax.servlet</groupId>
        <artifactId>servlet-api</artifactId>
        <version>2.4</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>javax.servlet.jsp</groupId>
        <artifactId>jsp-api</artifactId>
        <version>2.1</version>
        <scope>provided</scope>
    </dependency>
    <dependency>
        <groupId>com.google.caliper</groupId>
        <artifactId>caliper</artifactId>
        <version>0.5-rc1</version>
    </dependency>
    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjrt</artifactId>
        <version>1.7.1</version>
    </dependency>
    <dependency>
        <groupId>org.aspectj</groupId>
        <artifactId>aspectjweaver</artifactId>
        <version>1.7.1</version>
    </dependency>
</dependencies>

然后我运行 Maven 安装并上传了所有 nesssery 库。

下次我收到以下消息：

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.

当我尝试上课时，我得到了：Exception in thread "main" java.lang.NoClassDefFoundError: com/google/common/base/Splitter

请给我一个建议。

首先我看到你有一个错误：

阅读 C:\Users\User1.m2\repository\com\google\guava\guava\11.0.1\guava-11.0.1.jar; 无效的 LOC 标头（错误的签名）

这可能是由于下载 lib 过程中的失败引起的。解决方案是删除文件夹 C:\Users\User1.m2\repository\com\google 并重试构建。

此外，我看到您使用的是非常旧版本的 maven-compiler-plugin (2.0.2)，这使我得出结论，您没有配置 maven-compiler-plugin，这意味着您使用的是 java 1.4，但是您至少需要1.5。你必须像这样配置你的 maven-compiler-plugin：

<build>
  <pluginManagement>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.0</version>
        <configuration>
          <source>1.6</source>
          <target>1.6</target>
        </configuration>
      </plugin>
    </plugins>
  </pluginManagement>
</build>

也许您必须更改为1.5。
