Question

我下载了Jetty源并尝试运行以下maven命令：

mvn clean compile site -DskipTests -e

但问题是maven-site-plugin不起作用。我使用Maven 3.0.5（也尝试使用最新版本）和maven-site-plugin 3.3。

错误如下所示：

插件配置如下所示：

<plugin>
    <artifactId>maven-site-plugin</artifactId>
    <version>3.3</version>
    <executions>
      <execution>
        <id>attach-descriptor</id>
        <goals>
          <goal>attach-descriptor</goal>
        </goals>
      </execution>
    </executions>
</plugin>

所以看起来maven-site-plugin似乎仍然存在一些错误，它不能与Maven 3一起使用。有没有人知道任何解决方法呢？

请尝试package而不是compile

说明： Caused by: org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.apache.maven.plugins:maven-dependency-plugin:2.2:copy-dependencies (copy-lib-deps) on project jetty-ant: Error copying artifact from /jetty/jetty-io/target/classes to /jetty/jetty-ant/target/test-lib/jetty-io-9.1.3-SNAPSHOT.jar

工件尚未打包，因为您只编译了它，因此当尝试在表示目录的路径上复制jar时，m-dependency-p：copy-dependencies失败

当你运行包阶段时，jar会在这里，所以不再有任何问题
