I was trying to compile my URCap. Yesterday worked fine, but today it fails.

I encountered the same issue today. Googled the hell out of it, and tried several things. And finally found a solution in the following link. Change the pom.xml using the guide on [Trying to build docker image fails · Issue #150 · prometheus/cloudwatch\_exporter · GitHub](https://github.com/prometheus/cloudwatch_exporter/issues/150) Not sure if it is a good fix, or what it does, but it helped me to continue working.

Which POM.XML file did you have to change this in? and if it is in your project POM file where did you add it, because mine does not seem to contain the surefire plugin. I am having the same error as mentioned above ---

Nevermind I figured it out, thanks for the solution! ---

I have the same problem,could you tell me how you figured it ---

Hi Chao, You need to replace some code of your Pom.xml included in an urcap. For example, you may replace this: ``` org.apache.maven.plugins maven-compiler-plugin 3.6.0 1.6 1.6 TO THIS: org.apache.maven.plugins maven-surefire-plugin 2.22.1 false ``` ---

I don’t think you neceissarily need to replace a section with the “surefire” section. But inside the POM-file, there is a section called ``. It is generally like: ```auto ... some plugin ... some other plugin ``` In here, you need to add the `maven-surefire-plugin`. To make your POM contain this: ```auto ... some plugin org.apache.maven.plugins maven-surefire-plugin 2.22.1 alphabetical false ``` ---

i avoided this problem by compiling my code in the terminal with an added command: ``` mvn install -Dmaven.test.skip=true ``` rather than just using: ``` mvn install ``` It now compiles my caps just fine. ---

@sam.verity-hilton This is a good fix as well! Also works for me. ---

Yes, technically that works but … it will skip the test step now! I think that it is not a good idea to skip the test step. The option for ’ false is much better . This is also suggested on some java / maven forums as the best solution ---

@anon12495347 I agree its not a brilliant fix, but it was only temporary whilst the maven bug was fixed, which it is for me now, so I have reverted back to just using ``` mvn install ``` Though I never had any problems with caps compiled when the tests were skipped ---

Thank you,I have find the solution,I changed the command as mvn clean package -Dmaven.test.skip=true rather than mvn install and then it is ok!
