Question

我在Google Compute Engine中设置了Jenkins实例，以便在this page from Google之后构建和部署App Engine Java项目。

我已将Jenkins配置为仅在Maven构建成功时运行以下shell命令：gcloud --project=decent-ellipse-843 preview app deploy target/*-SNAPSHOT/

当我尝试构建时，部署失败并显示以下跟踪：

+ gcloud --project=decent-ellipse-843 preview app deploy target/backend-api-0.0.1-SNAPSHOT/

Maven构建成功，我可以通过手动发出gcloud命令来部署项目。

即使我从同一目录和同一用户（gcloud）下运行完全相同的tomcat命令，部署也会成功而没有错误。

我重新安装了python并更新了Google Cloud SDK而没有任何结果。

该实例运行的是Python 2.7.3，Jenkins 1.598，JDK 7u76和Maven 3.2.2。

我希望有人可以帮我解决这个问题！

我遇到了类似的问题，在cloud-dev-python slave上运行我的工作。这些图像缺少您可能需要的构建工具，以便正确构建和部署。我的解决方案是连接到docker镜像并第一次手动安装工具。

# on docker host, connect to java image
CONTAINER_ID=$(docker ps | grep cloud-dev-java | awk '{print $1}');
docker exec -i -t $CONTAINER_ID bash

# on docker image, install crap to build lxml, etc
gcloud -q components update preview app && apt-get update \
  && apt-get install -y build-essential libz-dev libxml2-dev \
  libxslt1-dev python-dev python-pip && apt-get autoremove

给它一个旋转，看看它是否有帮助。即使设置正确，我目前仍然坚持使用服务帐户进行身份验证...
