我在 Eclipse 中创建了 maven 项目并添加了一些依赖项。
这里是一个完整的依赖列表:
<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时:
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.

当我尝试运行我的类(class)时,我得到了:Exception in thread "main"java.lang.NoClassDefFoundError: com/google/common/base/Splitter
请给我一个建议。
最佳答案
首先我看到你有一个错误:
reading C:\Users\User1.m2\repository\com\google\guava\guava\11.0.1\guava-11.0.1.jar; invalid LOC header (bad signature)
可能是lib下载失败导致的。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的 maven-compiler-plugin (2.0.2) 版本,这让我得出结论,您没有配置 maven-compiler-plugin,这意味着您使用的是 java 1.4 但你至少需要 1.5。您必须像这样配置您的 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>
也许你必须换到 1.5。
