构建后生成的目标文件不包含必须存在的所有已编译类

【问题标题】：Generated target files after build doesn't contain all the compiled classes that must have been there构建后生成的目标文件不包含必须存在的所有已编译类
【发布时间】：2011-11-30 11:32:20
【问题描述】：

在构建项目时，控制台显示源包已编译（px10 包内的那个）

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clean & build 几次，但没有帮助
  2. 从.../var/cache/清除了netbeans缓存

这是构建 Web 应用时生成的日志

这个问题似乎是因为我从我自己创建的 web-inf 文件夹中删除了一个名为 classes 的文件夹。

【问题讨论】：

  • 我错过了与您的最后一段相关的一点：相对于此类 classes 文件夹的项目根目录的路径是什么？而且，您宁愿在此处粘贴 clean compile 日志，而不是 test 一个。 mvn clean compile -X 输出将是顶部，如果它是可管理的长度。
  • classes 的路径是 src/main/webapp/WEB-INF/classes/。在这个文件夹中，我放置了一些日志框架 (logback) 所需的配置文件。但是由于我将这些文件移到了其他地方，所以我只是删除了这个目录。我不是从命令行操作mvn，而是从netbeans 本身操作。上面打印的日志是我执行clean &amp; build时生成的。
  • 以上信息不足以帮助您解决问题。您要么需要包含pom.xml（最好转储有效POM），和/或向我们提供更详细的跟踪，如mvn clean compile -X。最好是第二个，如果您说某些文件无法进入 /target 文件夹。
  • 我尝试将 clean compile 输出放在这里，但它太大了，因此我放了有效的 POM 。让我知道是否需要更多。我应该输出mvn compile 吗？
  • 我相信mvn clean compile 会比你从netbeans 得到的输出更有用。我不是 netbeans 用户，但问题不太可能取决于该 IDE。无论如何，您可以通过在运行上述命令行后检查 /target 内容来轻松验证它。

【解决方案1】：

我发现问题是由于源包中的一些不可编译的类，因为没有类被复制到/target/classes/ 文件夹。在删除不可编译的源代码后，我发现它工作正常。

【讨论】：

    【解决方案2】：

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

    默认情况下（以及来自上面的 pom sn-p），它会将编译的类放在 target/classes 文件夹中。在战争项目的情况下，maven war plugin 将类复制到 webapp 内的WEB-INF/classes 文件夹。

    因此，在您的情况下，请检查以下文件夹：

    • C:\dev\ABCApp\target\classes
    • C:\dev\ABCApp\target\ABCApp\WEB-INF\classes

    【讨论】：

    • yes Raghuram .. 我检查了两个文件夹，但编译的 java 类不存在。
    • 事实上，现在我看到没有编译任何 java 类
    • @Marcos。我在上面的日志中看到“将 81 个源文件编译到 C:\dev\ABCApp\target\classes”。所以在构建结束之前还有其他东西正在删除它们
    • 是的...如果您在我的pom.xml 中看到有一个插件maven-antrun-plugin 可以自动编译协议缓冲区的.proto 文件。这些文件被复制到/classes 文件夹。
    • @Marcos。 antrun 在编译之前发生。运行 mvn test 后检查上面的文件夹，看看是否保留了类。如果没有，请尝试 mvn compile。这将有助于隔离问题
    【解决方案3】：

    某些版本的 maven-compiler-plugin 也会出现这种情况

    以下修复解决了我的问题，maven 现在可以正确报告编译器错误。 使用下面的注释版本，尽管代码不可编译，maven 仍会成功构建。

    <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>

      【解决方案4】：

      如果在使用 Spring Boot 应用程序构建 maven 项目的代码时未在 classes 文件夹中创建包。 某些版本的 maven-compiler-plugin 也会出现这种情况

      <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>
