How to get compiler warnings when creating a Jenkins plugin

Question

I am writing a Jenkins plugin but new to Java and Maven.

When I create a plugin in intelliJ, I get all the compiler warnings that I expect to see (for example, failure warnings), but I cannot find a way to compile it through the command line that will show them (for example, with mvn hpi: hpi / mvn compile)

I tried adding the following lines to the maven-compiler-plugin section of the Maven settings file, but to no avail:

<showDeprecation>true</showDeprecation>
<showWarnings>true</showWarnings>

The ultimate goal of this is to compile the plugin on jenkins and provide warnings to the alert plugin.

Answer 1

, :

1) - -Xlint: all:

<plugin>
 <groupId>org.apache.maven.plugins</groupId>
 <artifactId>maven-compiler-plugin</artifactId>
 <version>3.0</version>
 <configuration>
      <source>1.6</source>
      <target>1.6</target>
      <compilerArgument>-Xlint:all</compilerArgument>
      <showWarnings>true</showWarnings>
      <showDeprecation>true</showDeprecation>
  </configuration>
</plugin>

2.) :

mvn clean install -Dmaven.compiler.showDeprecation=true
