java - 手动删除目标文件夹后无法构建 Maven 项目

Question

我想签入svn中的代码并且不想保存二进制文件，所以我删除Target了由maven自动创建的文件夹。问题是自从我这样做以来，maven build 就失败了。

这是我尝试过的所有内容：

mvn clean install
mvn clean compile -DskipTests=true install
手动清理所有文件夹并重新构建。
Eclipse 能够构建它。

有趣的是，eclipse 不再显示标题Maven Dependencies为该项目的子节点，因为其他项目工作正常。我根本没有修改 POM 文件。

Pastebin 在此处被阻止，因此在此处附加构建输出。

任何帮助将不胜感激！

看起来您只<dependencyManagement>在 POM 中声明了一个部分。为了将依赖项实际添加到编译时类路径中，您还需要<dependencies>在 POM 根目录下的块中直接声明它们。

score 1 · Accepted Answer

在您的pom.xml中，您应该在顶级<dependencies>元素中指定依赖项，而不是在<dependencyManagement>元素中，如下所示：

<project>
    ...
    <url>
    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.8.2</version>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>log4j</groupId>
            <artifactId>log4j</artifactId>
            <version>1.2.14</version>
        </dependency>
        <!-- spring -->
        <dependency>
            <groupId>org.springframework</groupId>
