jenkins集成报错：java.lang.Object.wait(Native Method)之解决方案

 

 

继上一篇博客https://blog.csdn.net/u012366142/article/details/82756210的错误：

java.lang.Object.wait(Native Method)
 oracle.jdbc.driver.BlockSource$ThreadedCachingBlockSource$BlockReleaser.run(BlockSource.java:327)
18-Sep-2018 14:11:11.978 WARNING [localhost-startStop-1] org.apache.catalina.loader.WebappClassLoaderBase.clearReferencesThreads The web application [CAD_WebService] appears to have started a thread named [OracleTimeoutPollingThread] but has failed to stop it. This is very likely to create a memory leak. Stack trace of thread:

继续探究优化对jenkins的配置，改为使用SSH publishers进行war包部署，过程如下：

1.配置SSH Server

 

2.构建完成后，配置SSH Publishers

Exec command规则为：

./publish.sh <项目WEB显示名称> [TOMCAT端口] [tomcat安装主目录]

3.脚本文件publish.sh（存放在/usr/local/java/jenkins/workspace/target/下）

#!/bin/bash  
#defined
TOMCAT_HOME="/usr/local/java/tomcat8"
TOMCAT_PORT=8090
PROJECT="$1"
#param validate  
if [ $# -lt 1 ]; then
  echo "you must use like this : ./publish.sh  [tomcat port] [tomcat home dir]"    
  exit
fi
if [ "$2" != "" ]; then
   TOMCAT_PORT=$2
fi
if [ "$3" != "" ]; then
   TOMCAT_HOME="$3"
fi
#shutdown tomcat  
"$TOMCAT_HOME"/bin/shutdown.sh
echo "tomcat shutdown"  
#check tomcat process  
tomcat_pid=`/usr/sbin/lsof -n -P -t -i :$TOMCAT_PORT`
echo "current :" $tomcat_pid  
while [ -n "$tomcat_pid" ]  
do
 sleep 5
 tomcat_pid=`/usr/sbin/lsof -n -P -t -i :$TOMCAT_PORT`
 echo "scan tomcat pid :" $tomcat_pid  
done
#publish project  
echo "scan no tomcat pid,$PROJECT publishing"  
rm -rf "$TOMCAT_HOME"/webapps/$PROJECT*
cp /usr/local/java/jenkins/workspace/target/$PROJECT*.war "$TOMCAT_HOME"/webapps/$PROJECT.war
#bak project  
BAK_DIR=/usr/local/java/jenkins/workspace/target/bak/$PROJECT/`date +%Y%m%d`
mkdir -p "$BAK_DIR"
cp "$TOMCAT_HOME"/webapps/$PROJECT.war "$BAK_DIR"/"$PROJECT"_`date +%H%M%S`.war
#remove tmp  
rm -rf /usr/local/java/jenkins/workspace/target/$PROJECT*.war
#start tomcat  
"$TOMCAT_HOME"/bin/startup.sh
echo "tomcat is starting,please try to access $PROJECT conslone url"

该脚本具有自动安全停Tomcat,自动发布项目，自动备份已发布项目版本的功能

编辑脚本后，需要给用户赋予读写权限：

chmod 755 publish.sh

注意：

远程机器的java_home在配置在/etc/profile中的，这个只给shell用户使用的，但对于ssh 这种非login shell(non-login shell)用户，需要配置在/etc/bashrc中。

export JAVA_HOME=/usr/local/java/jdk1.8.0_181
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$PATH

至此，jenkins任务job便可正确构建并启动。
