这一切都发生在我尝试用 `./mvnw clean install`构建一个 Springboot 应用程序时

当我第一次运行 install 命令时，它遇到了以下问题。

我在 Stackoverflow 上搜索了这个问题，并通过邮件解决了这个问题

未能执行目标 org.apache.maven.plugins: maven- 编译器-插件: 2.3.2: 编译(默认-编译)

然后，我遇到了另一个问题

[ERROR] Source option 1.5 is no longer supported. Use 1.6 or later.
[ERROR] Target option 1.5 is no longer supported. Use 1.6 or later.

我在 OSX 上。 mvn -v节目:

最佳答案

You can specify maven source/target version by adding these properties to your pom.xml file

<properties>
<maven.compiler.source>1.6</maven.compiler.source>
<maven.compiler.target>1.6</maven.compiler.target>
</properties>

I think this means that

You are using JDK9 or later
Your project uses maven-compiler-plugin with an old version which defaults to Java 5.

You have three options to solve this

Downgrade to JDK7 or JDK8 (meh)
Use maven-compiler-plugin version or later, because

NOTE: Since 3.8.0 the default value has changed from 1.5 to 1.6 See https://maven.apache.org/plugins/maven-compiler-plugin/compile-mojo.html#target
```
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>
</plugin>
```
Indicate to the maven-compiler-plugin to use source level 6 and target 6 (or later).

Best practice recommended by https://maven.apache.org/plugins/maven-compiler-plugin/

Also note that at present the default source setting is 1.6 and the default target setting is 1.6, independently of the JDK you run Maven with. You are highly encouraged to change these defaults by setting source and target as described in Setting the -source and -target of the Java Compiler.
```
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
```
or use
```
<properties>
<maven.compiler.source>1.6</maven.compiler.source>
<maven.compiler.target>1.6</maven.compiler.target>
</properties>
```

There can be corrupted jar file for which it may show error as "ZipFile invalid LOC header (bad signature)" You need to delete all jar files for which it shows the error and add this Dependency

 <dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>3.0-alpha-1</version>
<scope>provided</scope>
</dependency>

This error might be also for plugin versions. You can fix it in the .POM file like the followings:

<build>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.1</version>
<configuration>
<source>1.6</source>
<target>1.6</target>
</configuration>
</plugin>
</plugins>
</build>

You need to set JDK 1.5 to your project and also all dependent project or jar file should also compiled with JDK 1.5

小开

For me the solution was to set the version of the maven compiler plugin to 3.8.0 and specify the release (9 for in your case, 11 in mine)

    <plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>3.8.0</version>
<configuration>
<release>11</release>
</configuration>
</plugin>

In IntelliJ:

Open Project Structure (⌘;) > Modules > YOUR MODULE -> Language level: set 9, in your case.
Repeat for each module.

Make sure you have following configuration in your pom.xml file.

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

I got this error: "Source option 5 is no longer supported. Use 6 or later" after I changed the pom.xml

<java.version>7</java.version>

<java.version>11</java.version>

Later to realise the property was used with a dash insteal of a dot:

  <source>${java-version}</source>
<target>${java-version}</target>

(swearings), I replaced the dot with a dash and the error went away:

<java-version>11</javaversion>

不再支持 ERROR Source 选项1.5。请使用1.6或更高版本
