安装nodejs
-
下载
wget https://nodejs.org/dist/latest-v8.x/node-v8.11.3-linux-x64.tar.gz
-
解压
tar -zxvf node-v8.11.3-linux-x64.tar.gz
-
创建软链接
cd node-v8.11.3-linux-x64/bin sudo ln -s node /usr/local/bin/node sudo ln -s npm /usr/local/bin/npm
-
查看版本
node -v npm -v
jenkins设定
- 新建job:省略
-
设定pom编译前执行的命令:
-
进入到工程目录,npm安装和webpack
cd jenkins下该项目的workspace npm install node_modules/.bin/webpack
-
出现错误1:
[INFO] --- maven-clean-plugin:2.6.1:clean (default-clean) @ testProject ---
[INFO]
[INFO] --- exec-maven-plugin:1.5.0:exec (npm install (initialize)) @ testProject ---
[ERROR] Command execution failed.
java.io.IOException: Cannot run program "npm" (in directory "/home/jenkins/workspace/testProject"): error=2, No such file or directory
- 解决:
在命令行查看npm -v就知道真相了。这是nodejs安装前,或是安装后没把命令放到/usr/local/bin时出的错误。
出现错误2:从jenkins控制台看信息,执行到npm install就没有下文了,一直跳舞中。。。
-
解决:进入命令行执行pom编译前执行的命令,即
# cd jenkins下该项目的workspace # npm install //出现了错误4 # node_modules/.bin/webpack 执行后,node_modules文件夹就出现在工程目录了。
-
注:
- 不知道根本原因,讲道理的话,在jenkins配置执行命令也该好使。
- 第一次在命令行执行后,下次jenkins编译就不会出这个问题了。
出现错误3:发布成功后,访问url,500错误,错误信息截取如下:
javax.servlet.ServletException: java.lang.LinkageError: loader constraint violation: when resolving method "org.apache.jasper.runtime.InstanceManagerFactory.getInstanceManager(Ljavax/servlet/ServletConfig;)Lorg/apache/tomcat/InstanceManager;" the class loader (instance of org/apache/jasper/servlet/JasperLoader) of the current class, org/apache/jsp/WEB_002dINF/jsp/login_jsp, and the class loader (instance of java/net/URLClassLoader) for the method's defining class, org/apache/jasper/runtime/InstanceManagerFactory, have different Class objects for the type org/apache/tomcat/InstanceManager used in the signature
at org.apache.jasper.servlet.JspServlet.service(JspServlet.java:358) ~[jasper.jar:8.0.9]
- 原因:外部tomcat的jar包与springboot内置tomcat的jar包冲突导致
-
解决: pom.xml修改
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-tomcat</artifactId> <scope>provided</scope> </dependency>
重新jenkins发布后,访问正常。
修改pom后,项目下WEB-INF/lib下的jar包没有了这仨包:tomcat-embed-core-8.5.11.jar, tomcat-embed-el-8.5.11.jar,tomcat-embed-websocket-8.5.11.jar
出现错误4:在命令行进入到项目的workspace执行npm install出现如下错误
Miscellaneous Warning ETIMEDOUT: request to https://registry.npmjs.org/karma-phantomjs-launcher fail
- 解决:
执行 $ npm config list
; cli configs
metrics-registry = "https://registry.npmjs.org/"
scope = ""
user-agent = "npm/5.6.0 node/v8.11.3 linux x64"
; node bin location = /usr/local/src/node-v8.11.3-linux-x64/bin/node
; cwd = /tmp/phantomjs
; HOME = /home/tomcat
; "npm config ls -l" to show all defaults.
执行 $ npm config set registry http://registry.npmjs.org/
执行 $ npm config list
; cli configs
metrics-registry = "http://registry.npmjs.org/"
scope = ""
user-agent = "npm/5.6.0 node/v8.11.3 linux x64"
; userconfig /home/tomcat/.npmrc
registry = "http://registry.npmjs.org/"
; node bin location = /usr/local/src/node-v8.11.3-linux-x64/bin/node
; cwd = /tmp/phantomjs
; HOME = /home/tomcat
; "npm config ls -l" to show all defaults.
