maven pom.xml write version to file-CodePudding

Assume we have this pom.xml detail, when we run mvn clean verify, we are able to retrieve the version "0.0.1-snapshot" from "${project.version}" tag and write to a file, however the file shows ending "%" for example 0.0.1-SNAPSHOT%. How do we remove ending "%". Been using maven-antrun-plugin.

Result:

example % cat log-ant-run.txt
0.0.1-SNAPSHOT%

CodePudding user response：

That is how MacOS "highlights" the absence of CR/LF in file:

 ~ % echo -ne test > test.txt
 ~ % cat test.txt
test%
 ~ %

but:

 ~ % echo test > test.txt 
 ~ % cat test.txt        
test
 ~ %
