Sonarqube scanner failing for SOME projects

[Mark Jaffe]

We are switching from an older Jenkins instance (1.646) to a newer one (2.121.3), and during addition of pipeline (Jenkinsfile) configuration, one of the projects succeeds, and most of the others are failing with error: 

[ERROR] Failed to execute goal org.sonarsource.scanner.maven:sonar-maven-plugin:3.5.0.1254:sonar (default-cli) on project myproject: Unable to execute SonarQube: Fail to download sonar-scanner-engine-shaded-7.2.1-all.jar to ?/.sonar/cache/_tmp/fileCache5699353903196323022.tmp: EOFException -> [Help 1]

Where the scan succeeds, I do not get that message; all projects share credentials, and I am using the following configuration in POM:

(for properties:)

<sonar.version>7.2.1</sonar.version>

<sonar.maven.version>3.5.0.1254</sonar.maven.version>

(for pluginManagent in <build> block:)

<plugin>

<groupId>org.sonarsource.scanner.maven</groupId>

<artifactId>sonar-maven-plugin</artifactId>

<version>${sonar.maven.version}</version>

<executions>

<execution>

<goals>

<goal>sonar</goal>

</goals>

</execution>

</executions>

</plugin>

The step in the Jenkinsfile for analysis is:

    stage('Test') {

      agent { docker mavenImage }

      steps {

        withCredentials([file(credentialsId: mavenCreds, variable: 'CREDS')]) {

          sh 'mv $CREDS ./settings.xml'

        }

        sh 'java -version ; mvn --version'

        sh 'mvn -B -s ./settings.xml -P sonar clean org.jacoco:jacoco-maven-plugin:prepare-agent install -Dmaven.test.failure.ignore=false  sonar:sonar'

      }

    }
