Maven 生成空 JAR
我有以下 pom 文件：
<build>
<defaultGoal>package</defaultGoal>
<sourceDirectory>src/web</sourceDirectory>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.0.2</version>
<configuration>
<includes>
<include>src/web/**/*.java</include>
</includes>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<outputDirectory>lib</outputDirectory>
</configuration>
</plugin>
</plugins>
</build>
我的源文件位于 src/web/org/myCompany/ 文件夹中。当我运行 pom 文件时，我生成了一个没有类文件的 JAR。我指定源目录的方式有什么问题？我没有收到任何错误消息，只是一个空 JAR（带有一些 META-INF 文件）。
顺便说一句，为什么maven在maven编译器插件上同时具有
I have the following pom file:
<build>
<defaultGoal>package</defaultGoal>
<sourceDirectory>src/web</sourceDirectory>
<plugins>
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.0.2</version>
<configuration>
<includes>
<include>src/web/**/*.java</include>
</includes>
</configuration>
</plugin>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<configuration>
<outputDirectory>lib</outputDirectory>
</configuration>
</plugin>
</plugins>
</build>
My source files are in the src/web/org/myCompany/ folder. When I run the pom file, I get a JAR generated with no class files. What is wrong with the way that I specified the source directories? I do not get any error messages, just an empty JAR (with some META-INF files).
On a sidenote, why does maven have both the <sourceDirectory> tag and the <include> tag on the maven compiler plugin? They seem to be redundant (except that the include tag allows multiple source directories).

尝试使用最新版本的
maven 编译器插件（删除< 后的部分如其他人所示？2.3.2怎么样？ ;configuration>无论如何，我认为
src/web。How about trying this with the latest version of
maven compiler plugin, which is2.3.2after removing the<includes><configuration>section as indicated by others?In any case, I think
<includes>would be a filter within the<sourceDirectory>and thus cannot havesrc/webspecified again.如果没记错的话，你不需要包含这些内容。 sourceDirectory 规范应该足够了。然后运行
If memory serves you don't need the includes. The sourceDirectory specification should be enough. Then run
