小贝子编程

构建后生成的目标文件不包含必须存在的所有已编译类



在构建项目时，控制台显示源包已编译(px10包中的那个)

但是，如果我看到生成的目标文件，则源包中没有任何类。

  1. 尝试了几次clean & build但没有帮助
  2. 清除.../var/cache/中的netbeans缓存

下面是构建web应用程序时生成的日志

这个问题似乎是由于我已经从我自己创建的web-inf文件夹中删除了一个名为classes的文件夹而引起的。

这是项目的有效POM:

            </configuration>
          </plugin>
        </plugins>
      </build>
    </profile>
  </profiles>
</project>

我发现这个问题是由于源包中的一些不可编译的类，因为没有一个类被复制到/target/classes/文件夹。在删除不可编译的源代码后，我发现它工作得很好。

maven不将生成的内容放在src/main/webapp/WEB-INF/classes文件夹中。

默认情况下(从上面的pom片段来看)，它将编译后的类放在target/classes文件夹中。在战争项目的情况下，maven war plugin将类复制到webapp中的WEB-INF/classes文件夹中。

所以，在你的情况下，检查以下文件夹:

  • C: 开发 ABCApp 目标类
  • C: 开发 ABCApp ABCApp web - inf 目标类

这也发生在某些版本的maven-compiler-plugin

下面的修复为我解决了这个问题，maven现在正确地报告编译器错误。使用下面的注释版本，maven将成功构建，尽管有不可编译的代码。

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.0</version>
    <!--This version will happily build successfully when the code fails to compile-->
    <!--<version>3.1</version>-->
</plugin>

在使用spring启动应用程序构建maven项目时，如果在classes文件夹中没有创建包。这也发生在某些版本的maven-compiler-plugin 

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.0</version>
    <!--This version will happily build successfully when the code fails to compile-->
    <!--<version>3.1</version>-->
          <configuration>
                <!--<skipMain>true</skipMain>-->
                <skip>true</skip>
                <source>1.8</source>
                <target>1.8</target>
            </configuration>
</plugin>
