compiler plugin

source ve target Tagleri

Açıklaması şöyle

Sometimes when you may need to compile a certain project to a different version than what you are currently using. The javac can accept such command using -source and -target. The Compiler Plugin can also be configured to provide these options during compilation.

Yani java derleyicisine geçilecek -source ve -target parametrelerini 2 şekilde tanımlayabiliyoruz.

1. Global Properties olarak

2. Plugin konfigürasyon parametreleri olarak

Global Properties

Örnek

Java 9 ile şöyle yaparız

<properties>
  <maven.compiler.release>11</maven.compiler.release>
</properties>

SpringBoot ile istersek, şöyle yaparız

<properties>
  <java.version>21</java.version>
</properties>

Açıklaması şöyle

<java.version> is not referenced in the Maven documentation. It is a Spring Boot specificity.

Bu eski yöntem. Şöyle yaparız

<properties>
  <maven.compiler.source>1.8</maven.compiler.source>
  <maven.compiler.target>1.8</maven.compiler.target>
</properties>

Plugin Configuration

Örnek - release tag

Şöyle yaparız

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.8.1</version>
    <configuration>
      <release>12</release>
    </configuration>
</plugin>

Örnek - source + target tag

Bu eski yöntem. Şöyle yaparız

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.11.0</version>
  <configuration>
    <source>1.8</source>
    <target>1.8</target>
  </configuration>
</plugin>

annotationProcessorPaths Tag

Örnek

Şöyle yaparız

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-compiler-plugin</artifactId>
  <version>3.8.0</version>
  <configuration>
    <source>19</source>
    <target>19</target>
    <encoding>UTF-8</encoding>
    <compilerArgs>
      <!-- Configure manifold plugin-->
      <arg>-Xplugin:Manifold</arg>
    </compilerArgs>

    <!-- Add the processor path for the plugin -->
    <annotationProcessorPaths>
      <path>
        <groupId>systems.manifold</groupId>
        <artifactId>manifold-json</artifactId>
        <version>${manifold.version}</version>
      </path>
    </annotationProcessorPaths>
  </configuration>
</plugin>
