-#### Java Maven: Sonatype legacy OSSRH
 
-1. Create an [OSSRH staging repository](https://central.sonatype.org/publish/publish-guide/).
-2. Create a GPG key to [sign the artifacts](https://central.sonatype.org/publish/requirements/gpg/). Save these for step 3.
-    - Install GnuPG: `brew install gnupg`
-    - Generate a key: `gpg --gen-key`. Note the key ID (e.g., `CA925CD6C9E8D064FF05B4728190C4130ABA0F98`) and short ID (e.g., `0ABA0F98`).
-    - Send the key: `gpg --keyserver keys.openpgp.org --send-keys <keyId>`
-    - Note: The following key servers can also be used: `keyserver.ubuntu.com`, `keys.openpgp.org`, or `pgp.mit.edu`
-    - Export the secret key: `gpg --export-secret-keys --armor <shortId> > secret_key.asc`
-    - The file `secret_key.asc` will contain the GPG secret key.
-3. Store the following secrets Github actions secrets: 
-    - `OSSRH_USERNAME` 
-    - `OSSRH_PASSWORD`
-    - `JAVA_GPG_SECRET_KEY`
-    - `JAVA_GPG_PASSPHRASE`
-4. In the [Speakeasy workflow file](/docs/workflow-file-reference), add `useSonatypeLegacy: true`:
-```yaml
-workflowVersion: 1.0.0
-speakeasyVersion: latest
-sources:
-    my_source.yaml:
-        inputs:
-            - location: my_source.yaml
-targets:
-    java:
-        target: java
-        source: my_source.yaml
-        publish:
-            java:
-                #add useSonatypeLegacy: true
-                useSonatypeLegacy: true
-                ossrhUsername: test
-                ossrhPassword: $ossrh_password
-                gpgSecretKey: $java_gpg_secret_key
-                gpgPassPhrase: $java_gpg_passphrase
-```
-5. In the java section of `gen.yaml`,  provide the additional configuration required for publishing to Sonatype legacy:
-```yaml
-    java:
-        #ensure the `groupID` matches the OSSRH org
-        groupID: com.example
-        #ensure the `artificatID` matches the artifact name:
-        artifactID: example-sdk
-        ossrhURL: https://s01.oss.sonatype.org/service/local/staging/deploy/maven2/
-        githubURL: github.com/org/repo
-        companyName: My Company
-        companyURL: https://www.mycompany.com
-        companyEmail: info@mycompany.com
