maven4 regression bug: script2.groovy: 1: unexpected char: '\' @ line 1, column 40. #34
Description
I have tested maven4 update (4.0.0-rc1) and found that groovy-maven-plugin stops working after this update:
Execution default of goal org.codehaus.gmaven:groovy-maven-plugin:2.1.1:execute failed: startup failed:
[ERROR] script2.groovy: 1: unexpected char: '\' @ line 1, column 40.
[ERROR] def parts = "1.5.12.0-SNAPSHOT".split("\.")
[ERROR] ^
[ERROR]
With maven 3.9 (e.g. 3.9.6 or 3.9.9) this used to work fine.
Configuration:
<plugin>
<groupId>org.codehaus.gmaven</groupId>
<artifactId>groovy-maven-plugin</artifactId>
<executions>
<execution>
<phase>generate-resources</phase>
<goals>
<goal>execute</goal>
</goals>
<configuration>
<source><![CDATA[
def versionSegments = "${project.version}".split("\\.")
...
]]>
</source>
</configuration>
</execution>
</executions>
</plugin>Can you confirm this bug? Is this really a bug of groovy-maven-plugin or is there a general bug in maven 4.0 resolving backslashes in POM (CDATA sections)?
p.s.: Using double quotes vs. single quotes for the regex string literal does not make any difference. It works with 3.9 and fails with 4.0.
