+When you are using multiple Sentry dependencies, you can avoid specifying the version of each dependency with a *BOM* or *Bill Of Materials*.
+
+Using Gradle 5.0 or higher, you can add the following to the `dependencies` section in your `build.gradle`:

+sidebar_order: 1000

+
+When you are using multiple Sentry dependencies, you can avoid specifying the version of each dependency with a *BOM* or *Bill Of Materials*.
+
+Using Maven, add the following to the `dependencyManagement` section in your `pom.xml`:
+
+```xml {tabTitle:Maven}{filename:pom.xml}
+<dependencyManagement>
+    <dependencies>
+        <dependency>
+            <groupId>io.sentry</groupId>
+            <artifactId>sentry-bom</artifactId>
+            <version>{{ packages.version('sentry.java', '5.1.0') }}</version>
+            <type>pom</type>
+            <scope>import</scope>
+        </dependency>
+    </dependencies>
+</dependencyManagement>
+```
+
+Then use dependencies without specifying a version, for example:
+
+```xml {tabTitle:Maven}{filename:pom.xml}
+<dependency>
+    <groupId>io.sentry</groupId>
+    <artifactId>sentry</artifactId>
+</dependency>
+<dependency>
+    <groupId>io.sentry</groupId>
+    <artifactId>sentry-logback</artifactId>
+</dependency>
+```
+
+Using Gradle 5.0 or higher, you can add the following to the `dependencies` section in your `build.gradle`:
+
+```groovy {filename:build.gradle}
+implementation platform('io.sentry:sentry-bom:{{ packages.version('sentry.java', '5.1.0') }}') //import bom
+implementation('io.sentry:sentry') //no version specified
+implementation('io.sentry:sentry-logback') //no version specified
+```
