Pull version in pom.xml

Question

I want to add the Jenkins build number to my file pom.xml. I can do this with the Maven Version plugin , but first I need the original version from the file pom.xml.

For this, I use the command xmllint --xpath '/project/version/text()' pom.xml. However, I keep gettingXPath set is empty

Here's an example file pom.xml:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <artifactId>das-artifact</artifactId>
  <name>das-name</name>
  <version>4.2</version>
</project>

And here is my conclusion:

$ xmllint --nsclean --xpath '/project/version/text()' pom.xml
XPath set is empty
$

However, if I change the item xmlnsto fooxmlns, it works:

Here's an example file pom.xml:

<project fooxmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <artifactId>das-artifact</artifactId>
  <name>das-name</name>
  <version>4.2</version>
</project>

And here is my conclusion:

$ xmllint --nsclean --xpath '/project/version/text()' pom.xml
4.2$

I am not too familiar with everything that can be done xmllint. Can I make it ignore the namespace attribute xmlns?

, , @A_Di-Matteo ( Maven 3.3.9 3.4.0, ), build-helper-maven-plugin, :

 mvn build-helper:parse-version versions:set \
     -DnewVersion=\${parsedVersion.majorVersion}.\${parsedVersion.minorVersion}.\${parsedVersion.incrementalVersion}-WhatEverYouLikeToAdd \
     versions:commit

Answer 2

local-name() xml- node.

Old-XPath: /project/version/text()
New-XPath: /*[local-name()="project"]/*[local-name()="version"]/text()

, bash,

$ xmllint --xpath '/*[local-name()="project"]/*[local-name()="version"]/text()' pom.xml
1.0.0-SNAPSHOT
