prettier-plugin-java: 2.6.8

prettier Test.md

Input:

# Java

```java
public class Test {

  public static void main(String[] args) {
    System.out.println("Hello, World!");
  }
}
```

# JavaScript

```javascript
function main() {
  console.log("Hello, World!");
}
```

Output:

# Java

```java
public class Test {

  public static void main(String[] args) {
    System.out.println("Hello, World!");
  }
}

```

# JavaScript

```javascript
function main() {
  console.log("Hello, World!");
}
```

Expected behavior:

# Java

```java
public class Test {

  public static void main(String[] args) {
    System.out.println("Hello, World!");
  }
}
```

# JavaScript

```javascript
function main() {
  console.log("Hello, World!");
}
```

Thank you for reporting this issue! I tried writing a simple unit test for this on the main branch, like so:

import { expect } from "chai";
import prettier from "prettier";
import javaPlugin from "../../../../src/index.js";

describe("Embed", () => {
  it("can format Java embedded in Markdown", async () => {
    expect(
      await prettier.format(
        `# Java

\`\`\`java
public class Test{public static void main(String[]args){System.out.println("Hello, World!");}}
\`\`\`
`,
        { parser: "markdown", plugins: [javaPlugin] }
      )
    ).to.equal(`# Java

\`\`\`java
public class Test {

  public static void main(String[] args) {
    System.out.println("Hello, World!");
  }
}
\`\`\`
`);
  });
});

However, the unit test succeeded. I then tried your sample with a .prettierrc.yaml like the following:

plugins:
  - ./prettier-java/packages/prettier-plugin-java/dist/index.js

On the main branch, this results in the expected result (no extra newline at the end of the Java code block), while on the prettier-plugin-java@2.6.8 tag, it results in the behavior you reported.

I believe this issue was resolved by #731 and so is OBE, but I will leave this open until the next release so that we can confirm with 100% certainty.

I just released prettier-plugin-java 2.7.1 and confirmed this issue is resolved (likely by #731 due to its better integration with Prettier's own framework/tools). Please try updating and let me know if you still see this issue.
