[yogeshl5481]

Facing similar issues with jdk1.7.0_55 and apache-maven-3.3.3 in Windows7 Below are plugin details:

1. maven-surefire-plugin : 2.19.1
2. cobertura-maven-plugin : 2.7 (error is same as previous comments in this issue thred)

Found same issues with 2.5.2 as well. log was different.

[ERROR] Cobertura: Error reading file C:\Users\workspace\Documents\Code\maven\owebdev\target\cobertura\cobertura.ser: null Error: Unable to read from data file C:\Users\workspace\Documents\Code\maven\owebdev\target\cobertura\cobertura.ser

I have close to 8500 classes in project.

cobertura.ser.lock file was present in target\cobertura

Issue does not occur when I reduce files to approx to 800

[MEZk]

The same error is happened on

jdk 1.7.0_95 and maven 3.2.5, LinuxMinx x64, cobertura maven plugin 2.7, surefire maven plugin 2.19.1. jdk 1.8.0_31 and maven 3.3.9, LinuxMinx x64, cobertura maven plugin 2.7, surefire maven plugin 2.19.1. jdk 1.8.0_72 and maven 3.3.9, LinuxMinx x64, cobertura maven plugin 2.7, surefire maven plugin 2.19.1. jdk 1.8.0_73 and maven 3.3.9, LinuxMinx x64, cobertura maven plugin 2.7, surefire maven plugin 2.19.1.

This workaround does not help. You can find the full pom.xml that I use here.

Further investigation (I use mvn clean cobertura:clean cobertura:cobertura command, jdk 1.8.0_73 and maven 3.3.9, LinuxMinx x64, cobertura maven plugin 2.7):

1. Setting surefire maven plugin version to 2.17 results in the same error.
2. Setting surefire maven plugin version to 2.17 + workaround results in the same error.
3. Setting surefire maven plugin version to 2.16 results in the same error.
4. Setting surefire maven plugin version to 2.15 results in the same error.
5. Setting surefire maven plugin version to 2.14 results in the same error.
6. Setting surefire maven plugin version to 2.13 results in the same error.
7. Setting surefire maven plugin version to 2.12 - OK!
8. Setting surefire maven plugin version to 2.11 - OK!.
9. Setting surefire maven plugin version to 2.10 - OK!

Facing the same problem...

• cobertura-2.1.1 (cobertura-maven-plugin 2.7)
• surefire 2.12.4
• jdk 1.8.0_92

No workaround found... (more memory allowed, cleaned workspace...)

[MEZk]

@NoxFr Try to set surefire version to 2.12 (not 2.12.4)

[NoxFr]

It seems to work for now with surefire 2.12... (2 builds in a row) Well... crossing fingers 😄 I would be interested to know why....
