java无法在docker内部构建gradle应用程序
我正在尝试从docker容器中使用gradle构建一个应用程序。 这是我的Dockerfile:
FROM openjdk:8-jdk
#install git
RUN apt-get install -y git
RUN git clone https://github.com/SFRJ/yurl.git
#install gradle
RUN wget https://downloads.gradle-dn.com/distributions/gradle-6.5-bin.zip
RUN unzip gradle-6.5-bin.zip
ENV GRADLE_HOME /gradle-6.5
ENV PATH $PATH:/gradle-6.5/bin
#compile and run app
RUN cd yurl
RUN gradle clean build --rerun-tasks --no-build-cache
ENTRYPOINT ["java", "-jar", "/yurlapp.jar"]
在执行build命令之前,一切都很顺利。它抛出以下内容:
Step 9/10 : RUN gradle clean build --rerun-tasks --no-build-cache
---> Running in a25d344c3571
Welcome to Gradle 6.5!
Here are the highlights of this release:
- Experimental file-system watching
- Improved version ordering
- New samples
For more details see https://docs.gradle.org/6.5/release-notes.html
Starting a Gradle Daemon (subsequent builds will be faster)
FAILURE: Build failed with an exception.
* What went wrong:
A problem occurred configuring root project ''.
> The project name must not be empty. Set the 'rootProject.name' or adjust the 'include' statement (see https://docs.gradle.org/6.5/dsl/org.gradle.api.initialization.Settings.html#org.gradle.api.initialization.Settings:include(java.lang.String[]) for more details).
* Try:
Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
* Get more help at https://help.gradle.org
BUILD FAILED in 3s
ERROR: Service 'yurlapp' failed to build: The command '/bin/sh -c gradle clean build --rerun-tasks --no-build-cache' returned a non-zero code: 1
我只是不明白那是什么。当我在docker外部运行相同的命令,但在docker内部失败时,应用程序构建得非常好。这不是一个多模块项目,不知道为什么它会抱怨rootProject
我可以确认我有一个设置。gradle文件里面有这个
rootProject.name = 'yurl'
这也是我的身材。格拉德尔

我不知道如何解决这个问题,我尝试了很多方法,但都没有效果。我需要使用gradle从docker内部构建此应用程序。我知道gradle安装正确,因为如果我在docker文件中添加version命令(RUN gradle-v),我可以在docker运行时看到打印的内容:

Build time: 2020-06-02 20:46:21 UTC
Revision: a27f41e4ae5e8a41ab9b19f8dd6d86d7b384dad4
Kotlin: 1.3.72
Groovy: 2.5.11
Ant: Apache Ant(TM) version 1.10.7 compiled on September 1 2019
JVM: 1.8.0_252 (Oracle Corporation 25.252-b09)
OS: Linux 4.18.0-25-generic amd64
因此,我的渐变和渐变的配置似乎还可以。另外,我知道git的安装和项目的克隆都很好,因为如果我在Dockerfile中添加一个运行ls-s,它将正确打印项目的所有内容
可能在构建中出现了问题。渐变或设置。格雷德尔档案。知道会是什么吗

你能试试下面的
Dockerfile
吗?因为有点变化问题是,您提到了一个stage
RUN cd yurl
,其中您正在更改一个目录,该目录仅对该特定stage有效,而对其余stage无效。如果您还想将该特定目录用于其他阶段。使用WORKDIR
运行我在上面所做的操作注意:-如果您只想在1个阶段中使用该目录,那么在1个阶段本身中使用类似
WORKDIR
的命令,而不是RUN cd DIR && ls -lart
