#MAVEN VERSIONS UPGRADE#
Equally, it is essential to upgrade the tooling we use to prevent malicious packages in our system. Make sure to pick the correct package and upgrade your dependencies in time. We shouldn’t take this for granted, as this is all a chain of trust when we have to deal with transitive dependencies. We use a lot of dependencies when developing software. Global (defined in the $/.m2/settings.xml or change the global settings.xml. The order for downloading repositories is described on the Repository Order Page as follows: This means that when a conflict is detected, Maven is allowed to use the conflict algorithms to choose the best version. Possible hijacking of downloads by redirecting to custom repositories.Domain hijacking when custom repositories are using abandoned domains.A man-in-the-middle attack (MITM Attack) due to the use of custom repositories over HTTP.From the release notes of Maven 3.8.1, Maven distinguished three separate issues: This is reported by Jonathan Leitschuh and documented in CVE-2021-26291.
Maven versions prior to 3.8.1 allowed users to connect to custom repositories using HTTP. The problem with HTTP repositories in older Maven versions We do see that a lot of people use Maven so not upgrading can end up in serious issues for a large part of the ecosystem. Luckily we found out in the JVM Ecosystem report 2021 that not many people work with Java 6 or below. Be aware that to run Maven 3.8.1, Java 7+ is required. If you are working in the Java ecosystem and building your applications with an older Maven version, this message is for you.Ĭheck your Maven version by typing mvn -version! If you are still running on an old Maven version like 3.6.3 or below you definitely need to upgrade to version 3.8.1 because of security reasons. Co-leading the Virtual JUG, NLJUG and DevSecCon community. Passionate about Java, (Pure) Functional Programming, and Cybersecurity.

#MAVEN VERSIONS SOFTWARE#
Downloading data-service:1.Java Champions & Developer Advocate and Software Engineer for Snyk. Maven will start building the project after downloading the latest SNAPSHOT of data-service. Let's open the command console, go to the C:\ > MVN > app-ui directory and execute the following mvn command. app-ui pom.xmlĪpp-ui project is using 1.0-SNAPSHOT of data-service.ĭata-service project is releasing 1.0-SNAPSHOT for every minor change.Īlthough, in case of SNAPSHOT, Maven automatically fetches the latest SNAPSHOT on daily basis, you can force maven to download latest snapshot build using -U switch to any maven command. In case of SNAPSHOT, Maven will automatically fetch the latest SNAPSHOT (data-service:1.0-SNAPSHOT) every time app-ui team build their project. To download the updated code, data-service version is be upgraded to 1.1. In case of Version, if Maven once downloaded the mentioned version, say data-service:1.0, it will never try to download a newer 1.0 available in repository.
#MAVEN VERSIONS CODE#
Now data-service team will release SNAPSHOT of its updated code every time to repository, say data-service: 1.0-SNAPSHOT, replacing an older SNAPSHOT jar.
#MAVEN VERSIONS DRIVER#
Unlike regular versions, Maven checks for a new SNAPSHOT version in a remote repository for every build. Binary JAR file downloads of the JDBC driver are available here and the current version with Maven Repository. SNAPSHOT is a special version that indicates a current development copy. To handle such kind of situation, SNAPSHOT concept comes into play.
#MAVEN VERSIONS UPDATE#
Now if data-service team uploads a new version every other day, then following problems will arise −ĭata-service team should tell app-ui team every time when they have released an updated code.Īpp-ui team required to update their pom.xml regularly to get the updated version. Now it may happen that team working on data-service is undergoing bug fixing or enhancements at rapid pace and they are releasing the library to remote repository almost every other day. For example, consider a team is working on the front end of the application as app-ui project (app-ui.jar:1.0) and they are using data-service project (data-service.jar:1.0). A large software application generally consists of multiple modules and it is common scenario where multiple teams are working on different modules of same application.
