eclipse - 未能执行目标 com.google.appengine:appengine-maven-plugin:1.9.67:devserver

问题描述

嘿，我在 devserver 和更新调用上启动我的 maven 项目时遇到问题。我构建了我的 Maven 项目以使用谷歌云引擎运行，但我遇到了这个问题并且无法启动我的服务器。这是我的 pom.xml ：

我认为它的 pom 文件有问题，因为错误说它找不到这个元素“com.google.appengine:appengine-maven-plugin:1.9.67:devserver”。因此，如果有帮助，这就是错误：

也许有人知道如何解决这个问题？

解决方案

添加

    <project>YOUR PROJECT ID</project>

确实也为我解决了这个问题，但是我没有使用较新的 gclod maven 插件，而是使用较旧的 appengine 插件：

    <groupId>com.google.cloud.tools</groupId>
    <artifactId>appengine-maven-plugin</artifactId>

与我的

    <groupId>com.google.appengine</groupId>
    <artifactId>appengine-maven-plugin</artifactId>

在某个时候，我可能应该继续使用 gcloud 插件，但现在我没有时间。

旧的 appengine 插件也适用于（未记录的）“项目”配置标签。从 1.9.67 及更高版本开始，由于他们的入门（开始示例）不起作用，谷歌的工作真的很混乱，而且工作也很糟糕。此外，如果从现在开始需要它，我们应该已经获得了一些关于它的信息。

作为记录，我发布了我的多模块/服务父 pom 片段，包括带有旧 appengine 插件的插件管理：

    <pluginManagement>
      <plugins>
          <plugin>
              <groupId>com.google.appengine</groupId>
              <artifactId>appengine-maven-plugin</artifactId>
              <version>${appengine.target.version}</version>
              <configuration>
                  <project>YOUR PROJECT ID</project> <!-- WHAT DO WE NEED THIS FOR-->
                  <jvmFlags>
                      <jvmFlag>-Ddatastore.backing_store=${project.basedir}/local_db.bin</jvmFlag>
                  </jvmFlags>
                  <fullScanSeconds>-1</fullScanSeconds>
              </configuration>
          </plugin>
      </plugins>
  </pluginManagement>
