今天发现了一个BUG，在引用其他的包的的时候报错：
ERROR - Undefined placeholders found in template: - Template: META-INF/autoconf/xxx.xml - Descriptor: META-INF/autoconf/xxx.xml - Base URL: jar:jar:file:/Users/liqiu/git/fmp/service/target/xxx.war!/WEB-INF/lib/123456.jar!/ --------------------------------------------------------------- -> undifined_version --------------------------------------------------------------- <jar:file:/Users/liqiu/git/fmp/service/target/xxx.war!/> Generating log file: META-INF/autoconf/auto-config.xml.log ERROR: undefined placeholders [INFO] ------------------------------------------------------------------------ [ERROR] BUILD ERROR [INFO] ------------------------------------------------------------------------ [INFO] Autoconfig failed
1、这个时候，发现123456.jar是外部载入的包，需要解压这个包
jar -xvf 123456.jar
2、然后查看文件：autoconf/xxx.xml，会发现确实存在这些变量没有被定义：${undifined_version}
3、在如下文件内添加这个变量
antx.properties、auto-config.xml
ERROR - Undefined placeholders found in template:
