| This is not a bug. Please don't use the Jenkins issue tracker to request help with configuration errors. When a bug report is misused to request help with a configuration error, it relies on a very small group of readers of bug reports to assist when a much larger group is available to assist on the Jenkins user mailing list and the Jenkins chat channels. I confirmed that Jenkins 2.176.2 starts and downloads all the suggested plugins as expected when the Install Suggested Plugins button is selected. Follow the instructions which are listed in the error message and install the plugins that are listed as "Fix this plugin first". Also, assure that you are running a supported version of Jenkins, either Java 8 or Java 11. The Jenkins project does not support Java 9, Java 10, Java 12, or Java 13. The plugin versions installed when I installed the suggested plugins with Jenkins 2.176.2 were: {normal} antisamy-markup-formatter:1.5 apache-httpcomponents-client-4-api:4.5.5-3.0 authentication-tokens:1.3 bouncycastle-api:2.17 branch-api:2.5.3 build-timeout:1.19 cloudbees-folder:6.9 command-launcher:1.3 credentials:2.2.0 credentials-binding:1.19 display-url-api:2.3.1 docker-commons:1.15 docker-workflow:1.18 durable-task:1.30 email-ext:2.66 git:3.10.1 git-client:2.8.0 github:1.29.4 github-api:1.95 github-branch-source:2.5.4 git-server:1.7 gradle:1.33 handlebars:1.1.1 jackson2-api:2.9.9.1 jdk-tool:1.3 jquery-detached:1.2.1 jsch:0.1.55 junit:1.28 ldap:1.20 lockable-resources:2.5 mailer:1.23 mapdb-api:1.0.9.0 matrix-auth:2.4.2 matrix-project:1.14 momentjs:1.1.1 pam-auth:1.5.1 pipeline-build-step:2.9 pipeline-github-lib:1.0 pipeline-graph-analysis:1.10 pipeline-input-step:2.10 pipeline-milestone-step:1.3.1 pipeline-model-api:1.3.9 pipeline-model-declarative-agent:1.1.1 pipeline-model-definition:1.3.9 pipeline-model-extensions:1.3.9 pipeline-rest-api:2.11 pipeline-stage-step:2.3 pipeline-stage-tags-metadata:1.3.9 pipeline-stage-view:2.11 plain-credentials:1.5 resource-disposer:0.13 scm-api:2.6.3 script-security:1.61 ssh-credentials:1.17.1 ssh-slaves:1.30.1 structs:1.19 subversion:2.12.2 timestamper:1.10 token-macro:2.8 workflow-aggregator:2.6 workflow-api:2.35 workflow-basic-steps:2.18 workflow-cps:2.72 workflow-cps-global-lib:2.14 workflow-durable-task-step:2.32 workflow-job:2.33 workflow-multibranch:2.21 workflow-scm-step:2.9 workflow-step-api:2.20 workflow-support:3.3 ws-cleanup:0.37{normal} |
